FX Panthera Black 700mm FAC – Precision-Focused PCP Performance
The FX Panthera Black 700mm FAC has been developed for shooters who expect exceptional precision, extensive adjustability, and a competition-inspired platform. Rather than being adapted from a conventional sporting air rifle, the Panthera platform was engineered around high-performance slug shooting and precision disciplines.
At the heart of the rifle, advanced FX engineering has been incorporated to create a stable and highly configurable shooting platform. Furthermore, a long 700mm barrel has been combined with the Dynamic Block system, adjustable regulator, precision trigger system, and competition-oriented chassis.
Consequently, the FX Panthera Black 700mm FAC is especially suited to experienced shooters who value consistency, balance, customisation, and repeatable performance.
Purpose-Built FX Panthera 700mm Platform
A dedicated precision platform has been created rather than a traditional hunting rifle simply being modified for increased power. As a result, the Panthera has been designed to accommodate the requirements of longer projectiles while maintaining the adjustability for which FX rifles have become known.
A Superior Heavy STX barrel liner is fitted to the 700mm configuration, while a larger Dynamic Block breech has been designed to accept projectiles measuring up to approximately 13mm in length. Therefore, greater flexibility is provided when compatible slug ammunition is being selected.
Meanwhile, the rifle’s extended barrel configuration provides the foundation required for efficient high-power setups.
Dynamic Block and High-Performance Airflow
Performance has been enhanced through the FX Dynamic Block system. Increased airflow can therefore be delivered efficiently to the projectile, while the high-power, short-impulse valve arrangement has been engineered to complement FAC-level configurations.
Additionally, tuning flexibility has been incorporated through the FX Quick Tune System.
Hammer-spring tension and regulator settings can consequently be matched more closely with the selected ammunition and desired setup. Nevertheless, tuning should always be carried out according to manufacturer guidance and applicable local regulations.
700mm Superior Heavy STX Barrel
A 700mm Superior Heavy STX barrel system is fitted to the FX Panthera Black 700mm FAC.
Because this configuration was developed with slug shooting in mind, the barrel platform has been designed to deliver the stability required for demanding precision applications. Furthermore, FX’s interchangeable liner architecture provides additional flexibility when compatible components are installed by an authorised FX dealer.
The 700mm configuration measures approximately 1245mm / 49 inches overall and weighs around 3.9kg / 8.55lb, depending on configuration and accessories.

Adjustable AMP MKII Regulator
Consistent air management plays an essential role in precision PCP shooting. Accordingly, the FX Panthera Black 700mm FAC has been equipped with the AMP MKII regulator.
Regulated pressure can be monitored using one of the rifle’s angled pressure gauges. At the same time, bottle pressure can be observed independently through the second gauge.
Because both gauges have been positioned for convenient visibility, essential pressure information can be checked without unnecessarily disturbing the shooting position.
Additionally, fine tuning can be achieved when the regulator is correctly matched with the hammer and ammunition setup.
300cc Carbon-Fibre Air Bottle
A removable 300cc carbon-fibre air bottle has been positioned at the rear of the rifle.
A maximum filling pressure of approximately 250 bar / 3,625 psi is supported, while refilling is handled through a conveniently positioned rear Foster quick-disconnect fitting.
Consequently, the rifle can be filled without complicated disassembly.
Shot count will naturally vary according to calibre, regulator setting, projectile weight, velocity and power configuration.
Competition-Inspired ARCA and M-LOK Fore-End
Accessory installation has been made particularly flexible on the Panthera.
An extended ARCA-style rail is incorporated into the fore-end, while M-LOK mounting sections are also provided. Therefore, compatible bipods, weights and other shooting accessories can be positioned according to the user’s preferred balance.
Furthermore, a barricade block has been placed close to the breech.
Additional balance adjustments can be achieved by fitting compatible external M-LOK weights or FX barrel-weight systems where appropriate.
As a result, the rifle can be configured for different precision-shooting positions instead of forcing every shooter into the same setup.
20 MOA Picatinny Optics Rail
Long-range optics have also been considered carefully.
A Picatinny scope rail with built-in cant is fitted to the Panthera platform. Consequently, suitable optics and mounting systems can be installed while preserving the rifle’s precision-focused character.
The extended rail system also allows scope position to be adapted according to eye relief and individual shooting style.
Naturally, optics, mounts and accessories should always be selected according to the rifle’s intended application.
Fully Adjustable and Ambidextrous Ergonomics
Comfort and repeatability have been prioritised throughout the rifle.
A fully adjustable buttstock is provided, while the cheekpiece can also be repositioned to achieve a more natural head position behind the optic.
Moreover, the sidelever cocking handle can be reversed for left-handed operation. The adjustable cheekpiece complements this configuration, allowing the rifle to accommodate a wider range of shooters.
A zero-angle AR-style grip is also supplied as standard.
Therefore, whether the rifle is being configured for supported target shooting, competition use or another lawful sporting application, the shooting position can be personalised more effectively.
Adjustable Match Trigger
Precise trigger control is particularly important when small groups are being pursued.
For that reason, an adjustable match trigger has been incorporated into the FX Panthera Black 700mm FAC.
Trigger characteristics can be configured within the manufacturer’s recommended settings so that a more controlled and predictable release can be achieved.
Combined with the rigid platform, adjustable stock and precision barrel system, the trigger contributes to a highly refined shooting experience.
Magazine Designed for Longer Projectiles
The Panthera’s Dynamic Block features a larger breech than earlier FX platforms.
Accordingly, projectiles measuring up to approximately 13mm in length can be accommodated. A deeper lid is also used on the Side-Shot magazine so that compatible longer slugs can be loaded.
Magazine capacity varies by calibre and configuration.
This flexibility is especially valuable for shooters who want to evaluate different compatible ammunition profiles and find the setup that performs consistently in their particular rifle.
Why Choose the FX Panthera Black 700mm FAC?
The FX Panthera Black 700mm FAC has been created for shooters who want significantly more adjustment than is normally offered by a conventional PCP rifle.
Instead of a fixed shooting configuration, an adaptable precision platform is provided.
Air pressure, hammer settings, stock position, cheekpiece height, optic position and rifle balance can all be tailored within the appropriate operating limits.
Furthermore, the long 700mm configuration, Superior Heavy STX liner, Dynamic Block and high-capacity plenum architecture provide a strong foundation for FAC-level performance where legally permitted.
At the same time, a professional black finish gives the rifle a purposeful, competition-oriented appearance.
Built for Precision-Focused Shooters
Ultimately, the FX Panthera Black 700mm FAC combines advanced PCP engineering with an exceptionally adjustable chassis.
Precision-oriented features have been incorporated throughout the platform, while practical controls have been positioned for convenient operation. Furthermore, the 300cc carbon-fibre bottle, AMP MKII regulator, Quick Tune System, adjustable match trigger, reversible sidelever and sophisticated rail system work together to create a highly configurable shooting platform.
For shooters seeking a premium FX rifle designed around precision and slug-oriented performance, the FX Panthera Black 700mm FAC represents a specialised option.
Calibre availability, muzzle energy, magazine capacity and certain specifications may vary between markets and configurations.

FX Panthera Black 700mm FAC Calibres, Power and Accessories
The FX Panthera Black 700mm FAC has been engineered as a highly configurable PCP platform, particularly for precision shooting with heavier pellets and airgun slugs. Its 700mm configuration uses the FX Superior Heavy STX barrel liner, while the Dynamic Block architecture has been designed to support high-flow air delivery and longer projectiles. FX documentation also shows Panthera barrel components for .177, .22, .25 and .30 calibre configurations, although exact factory availability can vary by country and dealer.
Available Calibres
Different calibre options allow the Panthera 700 to be configured around the shooter’s preferred ammunition and intended lawful shooting discipline.
Common Panthera calibre configurations include:
- .177 calibre / 4.5mm
- .22 calibre / 5.5mm
- .25 calibre / 6.35mm
- .30 calibre / 7.62mm
For many precision-focused users, .22 and .25 calibre configurations provide an attractive balance between projectile weight, air consumption and ballistic performance. Meanwhile, a .30 calibre configuration can accommodate substantially heavier projectiles where that calibre is legally permitted.
Importantly, FX states that although barrel liners are designed for quick replacement, complete calibre changes and different barrel-length installations should be performed by an authorised FX dealer. This requirement helps ensure that the probe, barrel, shroud, plenum and associated components remain correctly matched.
FAC Power Configuration
The term FAC is generally used for air rifles configured above certain lower-power legal thresholds in markets where higher-powered airguns are regulated.
Rather than being defined by one universal muzzle-energy figure, the output of the FX Panthera Black 700mm FAC depends on multiple variables. Calibre, projectile weight, regulator setting, hammer configuration, barrel setup and ammunition choice can all influence muzzle velocity and energy.
Because the Panthera platform uses an adjustable AMP MKII regulator, Quick Tune System and high-flow Dynamic Block architecture, the rifle can be tuned across a broad performance range. However, any adjustment should remain within manufacturer specifications and applicable local law.
Furthermore, exact factory power figures should always be checked for the specific calibre and market version being purchased. This is especially important because legal limits, dealer configurations and approved specifications differ between countries.
Large Plenum and High-Flow Air System
Air delivery plays a major role in the Panthera’s performance.
The Panthera uses FX’s plenum-over-barrel design, with up to approximately 156cc of plenum volume according to FX. By surrounding part of the barrel with the plenum assembly, a rigid system is produced while a substantial reserve of regulated air is made available for each shot.
Consequently, the design is particularly well suited to heavier projectiles and higher-power applications.
A 300cc carbon-fibre bottle is supplied on the standard platform, with a stated working pressure of up to 250 bar. Larger compatible FX bottles are also listed among available accessories, including 480cc and 580cc versions, although compatibility and balance should be confirmed before installation.
Slug-Focused 700mm Barrel System
A major strength of the Panthera 700 is its slug-oriented barrel configuration.
The 700mm Superior Heavy STX liner has been selected specifically for increased stability with heavier projectiles. Additionally, the Dynamic Block breech has been enlarged so that compatible projectiles measuring up to approximately 13mm in length can be accommodated.
A deeper Side-Shot magazine lid is consequently used to provide additional clearance for longer ammunition.
Because projectile performance can vary considerably between rifles, ammunition testing is normally required to identify the most consistent combination for a specific setup.
Accessories for the FX Panthera Black 700mm FAC
A wide selection of accessories can be fitted to personalise the Panthera for precision shooting, competition use or other lawful sporting applications.
The chassis incorporates a full-length ARCA rail together with M-LOK mounting slots, allowing compatible equipment to be positioned along the fore-end.
Recommended Compatible Accessories
Popular Panthera accessories include:
- FX M-LOK balancing weights
- FX Dynamic barrel weights
- Bag rider
- Offset M-LOK weights
- Competition Mini-Mag
- Picatinny accessory rail sections
- Compatible bipods
- ARCA-mounted shooting supports
- 300cc FX carbon-fibre bottle
- 480cc FX carbon-fibre bottle
- 580cc FX carbon-fibre bottle
- Compatible FX barrel kits

- Optional tungsten hammer
- FX Panthera/Dynamic power-kit components where appropriate
FX specifically lists accessories such as the bag rider, barrel weights, offset M-LOK weights, Mini-Mag, Picatinny sections and optional tungsten hammer for Panthera customisation.
Barrel Kits and Calibre Conversion Components
For shooters seeking additional flexibility, FX offers Dynamic-family barrel kits that are compatible with the Panthera platform.
These kits can include a calibre-specific probe, barrel liner, matching plenum and dedicated shroud, allowing the system to remain properly matched to the chosen barrel length and calibre.
Consequently, the rifle can be adapted to different shooting requirements without replacing the entire platform. Nevertheless, FX specifies that calibre and barrel-length conversions should be completed by an authorised dealer.
A Highly Configurable Precision Platform
Ultimately, the FX Panthera Black 700mm FAC combines multiple calibre possibilities, sophisticated air management and extensive accessory compatibility within one precision-focused platform.
Its 700mm Superior Heavy STX barrel, large plenum, AMP MKII regulator, Dynamic Block and Quick Tune System provide the mechanical foundation for serious PCP performance. Meanwhile, ARCA and M-LOK interfaces make balance and accessory placement highly adaptable.
Whether a .22, .25 or .30 calibre configuration is selected, the Panthera can therefore be tailored around different projectile weights, shooting styles and legal power requirements. Exact muzzle energy, calibre availability and approved FAC configuration should always be confirmed for the specific market before purchase or use.
Practical Use Scenarios for the FX Panthera Black 700mm FAC
The FX Panthera Black 700mm FAC is designed for shooters who want a configurable precision air rifle that can be adapted to different lawful sporting and recreational environments. Its long 700mm barrel, adjustable stock, regulated PCP system, ARCA rail, M-LOK mounting points, and precision-oriented chassis make it especially suitable for organised target shooting, benchrest work, competition practice, and controlled range use.
Rather than being limited to one shooting position or one style of setup, the Panthera can be configured around the shooter, the supporting equipment being used, and the type of target discipline being practised. Because balance, cheek height, stock position, optic placement, and accessory position can all be adjusted, a repeatable shooting position can be created more easily.
Precision Target Shooting at the Range
One of the most natural environments for the Panthera is a properly managed shooting range.
For example, a shooter may arrive at the range with the rifle already fitted with a suitable optic, bipod, and rear support. Once the shooting lane has been confirmed as safe, the rifle can be placed on the bench and the stock can be adjusted until the user’s shoulder position feels comfortable.
The cheekpiece can then be positioned so that a consistent eye line is maintained behind the optic.
Because the Panthera is built around a long, rigid precision platform, the rifle can remain stable when supported properly. This is particularly useful during slow, deliberate target sessions where consistency matters more than rapid shooting.
A shooter may begin by firing a carefully controlled group at a known distance. Afterward, the target can be reviewed so that ammunition consistency, optic setup, and overall rifle behaviour can be evaluated.
Instead of constantly changing the rifle, experienced users will normally keep one configuration stable long enough to understand how it performs.
Benchrest Shooting
Benchrest shooting is another practical application for the Panthera 700mm.
When the rifle is placed on a stable shooting bench, the long fore-end provides generous room for positioning a bipod, front rest, or compatible ARCA-mounted support. Meanwhile, the adjustable rear section allows the shooter to establish a consistent shoulder and cheek position.
This setup can be useful when small shot groups are being evaluated.
For instance, several different compatible pellets or airgun slugs may be tested under the same range conditions. Each ammunition type can be assessed for consistency, grouping, and reliability without changing multiple variables at once.
Because the Panthera uses a regulated PCP system, predictable air delivery can support repeatable shooting when the rifle is properly set up.
Additionally, the dual pressure gauges make it easier to monitor the remaining air supply and regulated system pressure.
A typical bench session may therefore involve a measured sequence of shots, target inspection, notes on group size, and careful comparison between ammunition types.
Competition Practice
The competition-inspired chassis makes the Panthera especially attractive for structured practice.
A shooter preparing for a precision airgun event may need to work from several supported positions. In these situations, the ARCA rail can be particularly useful because compatible accessories can be moved along the fore-end to suit different support points.
For example, the bipod may be positioned farther forward for a stable prone or bench position. At another stage, a different support accessory may be positioned closer to the rifle’s centre of balance.
External balance weights can also be used where permitted by the competition rules.
This allows the rifle’s handling characteristics to be adjusted according to the shooter’s preferred setup.
However, the objective is not simply to add more equipment. Instead, the goal is to create a balanced platform that remains predictable from shot to shot.
Long-Range Airgun Target Practice
Where local regulations and range rules permit, the Panthera 700mm can also be used for extended-distance target practice.
A suitable range with a secure backstop should always be selected for this type of shooting.
At longer distances, small inconsistencies become more noticeable. Wind conditions, projectile selection, rifle stability, optic setup, and shooter technique all influence the final point of impact.
For this reason, longer-range shooting is often approached methodically.
A shooter might begin at a known shorter distance to confirm the optic setup. Once the rifle is performing consistently, targets can then be placed progressively farther away within the approved range.
The process can be used to understand projectile behaviour and to improve consistency.
Because the Panthera is designed around a rigid chassis and a 700mm barrel configuration, it offers the physical platform required for this type of disciplined range work.
Ammunition Testing
Another practical use involves comparing compatible pellets and airgun slugs.
Not every projectile performs identically in every rifle.
Differences in diameter, weight, profile, manufacturing consistency, and barrel compatibility can influence accuracy.
Therefore, a controlled testing session can be valuable.
The rifle may first be filled to an appropriate pressure according to manufacturer guidance. One ammunition type can then be tested over several carefully aimed groups.
Afterward, another compatible projectile can be tested under the same conditions.
By keeping the shooting distance, support position, optic setting, and environmental conditions as consistent as possible, useful comparisons can be made.
This process is especially relevant to a rifle such as the Panthera because the platform has been designed to accommodate longer projectiles and heavier slug-oriented configurations.
Supported Prone Shooting
The Panthera can also be used effectively from a supported prone position.
When a compatible bipod is attached to the fore-end, the rifle can be positioned low to the ground while the shooter maintains a stable body position behind it.
The adjustable stock and cheekpiece can help reduce unnecessary movement between shots.
For target practice, this can be useful because the shooter can concentrate on breathing, sight alignment, trigger control, and follow-through.
A rear support bag may also be used where appropriate.
The long overall dimensions of the Panthera are generally best suited to deliberate, supported shooting rather than quick handling in confined spaces.
Consequently, open range environments provide a more natural setting for the rifle.
Training for Consistency
The Panthera is also well suited to shooters who want to improve consistency rather than simply concentrate on power.
A structured training session can include repeated attention to the same fundamentals.
For instance, the rifle can be positioned identically on the bench for each shot. The user’s cheek position can remain consistent, shoulder pressure can be controlled, and the trigger can be operated smoothly.
Over time, these repeated actions can help reveal whether changes in group size are coming from shooter technique, environmental conditions, ammunition variation, or equipment setup.
This is one reason adjustable rifles can be valuable for experienced shooters.
The equipment can be fitted to the shooter rather than forcing the shooter to adapt to a fixed stock position.
Optic Setup and Zero Confirmation
The Panthera’s Picatinny optics rail allows a wide range of compatible scopes and mounting systems to be fitted.
A practical range session can therefore include optic installation, eye-relief adjustment, and zero confirmation.
Initially, the scope should be mounted securely using appropriate rings and manufacturer guidance.
The adjustable stock and cheekpiece can then be configured so that a natural sight picture is obtained.
After the rifle has been set up correctly, a paper target can be used for confirmation.
Small adjustments can be made until the point of impact corresponds with the intended sight setting.
Once established, the same setup can be used repeatedly for future range sessions.
Using the ARCA Rail for Support
The full-length ARCA-style fore-end is one of the Panthera’s most useful practical features.
Compatible bipods, tripods, and other shooting supports can be attached or repositioned without needing several separate mounting systems.
For bench shooting, a bipod may be placed toward the front.
For another supported position, it may be moved rearward.
Likewise, compatible shooting rests can be installed where range rules permit.
The benefit is flexibility.
Instead of having one fixed mounting position, the shooter can experiment with support placement until the rifle feels balanced and stable.
Balance Adjustment
The Panthera’s modular chassis also allows compatible weights to be installed in selected positions.
This can be useful when a heavy optic, larger air bottle, bipod, or other accessory changes the balance of the rifle.
For example, a shooter may feel that the front end has become too light after a particular setup change. Compatible weights can then be positioned forward to restore the desired balance.
Alternatively, the system may be kept lighter for easier transport.
Finding the right balance is highly personal, which is why the Panthera’s modular design is valuable.
Club and Organised Shooting
For members of shooting clubs, the Panthera can serve as a dedicated precision rifle for structured practice sessions.
Club ranges often provide controlled distances, approved targets, established firing lines, and experienced range officers.
These environments are particularly suitable for a high-performance PCP platform.
A shooter can arrive with the rifle stored securely in an appropriate case, set up at the allocated firing point, and follow the range’s normal safety procedures.
The rifle can then be used for group testing, scoring exercises, competition preparation, or supervised practice.
Chronograph-Based Performance Checking
Where permitted and carried out safely, a chronograph can be used to check shot-to-shot consistency.
The purpose of this type of session is not simply to seek the highest possible output.
Instead, the data can help reveal whether the rifle is operating consistently within the manufacturer’s specifications and the applicable legal limits.
Velocity readings can be recorded over a string of shots.
If the results remain closely grouped, the rifle’s air delivery is likely to be operating consistently.
Any significant irregularities can then be investigated by a qualified technician or authorised FX dealer.
Routine Range-Day Setup
A typical day with the Panthera may begin before the rifle ever reaches the firing line.
The air cylinder can be checked, the optic inspected, mounting hardware confirmed, and approved ammunition prepared.
Once at the range, the rifle can be removed from its case only in the designated area.
The bipod or other support can then be installed, while the stock and cheekpiece can be checked for the correct position.
After the range is declared active, shooting can begin.
Following the session, the rifle should be made safe and stored according to applicable local requirements.
A Platform for Experienced Precision Shooters
Ultimately, the FX Panthera Black 700mm FAC is best understood as a specialised precision platform.
Its practical value comes from the combination of a long 700mm barrel, regulated PCP system, adjustable ergonomics, modular accessory mounting, and competition-oriented chassis.
For benchrest sessions, organised target competitions, prone practice, ammunition evaluation, optic setup, and extended-distance target work, the rifle offers considerable flexibility.
Rather than being limited to one configuration, it can be adapted around the shooter’s preferred lawful discipline.
That versatility makes the Panthera especially attractive to users who value repeatability, careful equipment setup, and structured precision shooting.
As with any FAC-rated air rifle, use should always remain within local laws, range requirements, safe backstop practices, and manufacturer recommendations.
Frequently Asked Questions
What is the FX Panthera Black 700mm FAC?
The FX Panthera Black 700mm FAC is a high-performance pre-charged pneumatic air rifle designed around precision shooting, advanced adjustability, and a competition-inspired chassis. A 700mm barrel configuration is used, while the platform is built to support heavier pellets and compatible slugs.
Unlike a conventional sporting air rifle, the rifle is structured around a modular chassis that allows the shooting position, balance, optics, and support equipment to be adjusted according to the user’s requirements.
The black finish gives the rifle a clean, professional appearance, while the combination of the Dynamic Block, regulated air system, long barrel, and adjustable stock makes it suitable for demanding range applications.
What does FAC mean on this rifle?
FAC generally refers to a higher-powered configuration that may be subject to licensing or additional legal requirements depending on the country in which the rifle is sold or used.
The exact legal definition is not universal. Consequently, buyers should always confirm the regulations that apply in their own jurisdiction before purchasing, transporting, or using a higher-powered air rifle.
Power output can also vary according to calibre, factory configuration, projectile weight, and market specification. Therefore, one fixed energy figure should not automatically be assumed for every version.
What calibres are available?
Several calibre configurations may be offered depending on dealer availability and regional restrictions.
Common options associated with the platform include .177, .22, .25, and .30 calibre configurations. However, not every calibre will necessarily be stocked in every market.
Many shooters select a calibre according to their preferred target discipline, projectile availability, range distance, and local legal requirements.
For the best results, buyers should confirm the exact calibre supplied before ordering.
Is the 700mm barrel suitable for precision shooting?
Yes. The 700mm barrel configuration has been developed with precision and efficient air use in mind.
The longer barrel can support stable projectile acceleration and is particularly relevant to configurations designed around heavier pellets or slugs. In addition, the long format complements the rifle’s competition-oriented chassis and supported shooting positions.
Nevertheless, accuracy depends on more than barrel length alone. Ammunition quality, optic setup, rifle condition, shooting technique, environmental conditions, and proper adjustment all contribute to final performance.
Can pellets and slugs both be used?
Compatible pellets and slugs may be used when they match the rifle’s calibre and barrel configuration.
The rifle has been designed with slug shooting as a major consideration, especially through the longer-projectile compatibility offered by the Dynamic Block system.
However, different projectiles can behave differently in the same rifle. As a result, testing several suitable options may be necessary before the most consistent ammunition is identified.
Only projectiles that are appropriate for the rifle’s calibre and specifications should be selected.
Is the rifle regulated?
Yes. A regulated air-management system is incorporated into the platform.
The regulator helps control the pressure supplied for each shot so that greater consistency can be achieved throughout the usable fill range.
More consistent air delivery can contribute to predictable velocity and tighter groups when the rifle is correctly configured.
The regulator should be adjusted only in accordance with manufacturer guidance and applicable legal limits.
What air bottle is supplied?
A carbon-fibre air bottle is typically fitted to the rifle.
The standard setup is commonly associated with a 300cc bottle, although exact equipment may differ according to version or retailer package.
Carbon-fibre construction helps reduce unnecessary weight compared with heavier cylinder materials while still providing useful air capacity.
Compatible larger bottles may also be available, although fitment and balance should be confirmed before installation.
What is the maximum fill pressure?
The rifle is designed around a high-pressure PCP system, with a maximum fill pressure typically listed at around 250 bar for the standard configuration.
Users should always follow the pressure markings and official manufacturer instructions that accompany the specific rifle and cylinder.
Overfilling should never be attempted.
A compatible filling system, properly rated equipment, and appropriate PCP filling procedures should always be used.
Does the rifle have adjustable power?
The platform offers significant tuning capability through its regulator and external adjustment systems.
However, adjustments should not be treated simply as a method of maximising output.
The most useful setup is normally the one that provides consistent performance with the selected ammunition while staying within the rifle’s approved specifications and local law.
If significant configuration changes are required, assistance from an authorised dealer or experienced airgun technician is recommended.
What is the Dynamic Block?
The Dynamic Block is a key part of the rifle’s action and airflow system.
It has been developed to support increased airflow and longer compatible projectiles compared with more conventional designs.
The larger breech architecture can accommodate projectiles of greater length, which is particularly useful for users interested in specialised airgun slugs.
This design is one reason the rifle is often selected for precision-focused PCP applications.
Does it have an adjustable trigger?
Yes. An adjustable match-style trigger is fitted.
The trigger is designed to provide a clean and predictable release when correctly adjusted.
A consistent trigger pull can be particularly useful for benchrest and precision target shooting because unnecessary movement during the shot can be reduced.
Adjustments should be kept within the manufacturer’s recommended limits.
Is the stock adjustable?
Yes. Considerable stock adjustment is available.
The buttstock and cheekpiece can be repositioned so that a more natural shooting position can be established.
This can help users achieve more consistent shoulder placement and eye alignment behind the optic.
Because body dimensions and shooting styles vary, adjustability can make the rifle more comfortable for a broader range of users.
Is the rifle suitable for left-handed shooters?
The platform offers a high level of ambidextrous usability.
The sidelever system can be configured to suit different user preferences, while the cheekpiece and stock adjustments can also help accommodate left-handed shooting positions.
Exact conversion procedures should be carried out according to manufacturer instructions.
This flexibility makes the rifle more inclusive for users who prefer different operating layouts.
