Weihrauch HW100X T Thumbhole Synthetic Black Adjustable
The Weihrauch HW100X T Thumbhole Synthetic Black Adjustable is a pre-charged pneumatic air rifle developed as part of the updated HW100 X platform. Building on the established HW100 design, the X-series introduces changes to the air system, regulator, cylinder construction, handling characteristics, and overall efficiency while retaining the familiar multi-shot configuration associated with the HW100 family.
A black synthetic thumbhole stock is fitted to this version, while soft grey inserts have been incorporated into the stock to provide additional grip around key handling areas. Furthermore, an adjustable buttplate is included so that the stock position can be adapted to different users and shooting positions.
The rifle is designed for right- and left-handed use, making the stock arrangement comparatively versatile. Because the HW100X platform is powered through a pre-charged pneumatic system, recoil and mechanical vibration are substantially different from those experienced with traditional spring-powered air rifles.
Updated HW100 X PCP Platform
Several engineering changes distinguish the Weihrauch HW100X T Thumbhole Synthetic Black Adjustable from earlier generations of the HW100.
Most notably, a high-grade aluminium air cylinder has been introduced. A maximum filling pressure of 250 bar is specified for the current HW100 X platform. Compared with earlier configurations, the aluminium construction also contributes to reduced overall system weight.
Additionally, the regulator has been redesigned. The regulator controls the delivery of compressed air during each firing cycle, helping maintain a more consistent operating cycle as the pressure inside the cylinder changes.
Weihrauch states that the X-series provides at least a 50% increase in firing capacity compared with previous HW100 configurations, although the exact usable shot count depends on the particular calibre, configuration, market specification, and operating conditions.

Black Synthetic Thumbhole Stock
One of the defining characteristics of this model is its black synthetic thumbhole stock.
Unlike traditional walnut stocks, the synthetic design provides a uniform structure that is less dependent on natural wood grain. For users who regularly handle sporting equipment in varying environmental conditions, synthetic construction can also simplify routine exterior care.
Soft grey inserts are positioned within the stock design. These sections provide additional texture while also distinguishing the black-and-grey appearance of the rifle.
The thumbhole configuration allows the firing hand to sit naturally around the pistol-grip section of the stock. Consequently, a stable interface between the shooter and the rifle can be maintained without requiring an overly complicated stock profile.
Adjustable Buttplate
An individually adjustable buttplate is incorporated into the synthetic thumbhole stock.
Adjustment allows the rear contact point of the stock to be altered to better suit an individual user’s body position and preferred shooting posture. This feature can be particularly useful when the rifle is used during structured target practice where repeatable positioning is important.
The stock has also been designed for both right- and left-handed users.
14-Shot Magazine System
A 14-shot magazine is used across the current HW100 X platform.
The magazine allows multiple pellets to be loaded into the rifle’s repeating system before another magazine needs to be prepared. Cycling is carried out through the Biathlon-style lever fitted to the action.
This arrangement separates the loading cycle from the firing operation and provides a clearly defined mechanical sequence.
Before any magazine is inserted, removed, loaded, or inspected, the rifle should always be kept pointed in a safe direction and handled according to the manufacturer’s safety instructions.
Two-Stage Adjustable Match Trigger
A two-stage adjustable match trigger is fitted to the Weihrauch HW100X platform.
Two-stage triggers provide a clearly separated initial movement followed by a defined second stage. The arrangement can assist with predictable trigger operation during controlled sporting and target use.
A manual safety system is also incorporated.
Any trigger or safety adjustment should only be carried out according to the manufacturer’s documentation. Internal modifications should not be attempted unless the work is being performed by an appropriately qualified technician.
Redesigned Regulator
Consistency is an important part of a regulated PCP system.
Within the Weihrauch HW100X T Thumbhole Synthetic Black Adjustable, the updated regulator manages compressed-air delivery from the main cylinder into the firing system.
Rather than allowing the changing cylinder pressure to directly determine each operating cycle, the regulator provides controlled pressure to the action. This contributes to the repeatable behaviour expected from a regulated PCP platform.
The regulator forms part of the major technical update introduced with the HW100 X generation.
250-Bar Aluminium Air Cylinder
Compressed air is stored inside an aluminium cylinder rated for filling to 250 bar on the current HW100 X platform.
The cylinder includes an integral pressure gauge, allowing its pressure status to be checked visually. Quick-fill equipment is also incorporated into the system.
Because compressed-air systems operate at very high pressure, filling procedures should always follow the instructions supplied by Weihrauch. Appropriate filling equipment rated for the required pressure must be used, and the cylinder’s inspection and service requirements should never be ignored.
Scope Mounting Arrangement
Depending on the specific HW100 X version and regional configuration, Weihrauch lists scope mounting through either a Picatinny rail or an 11 mm prism/dovetail arrangement.
The correct mounting hardware must therefore be selected according to the exact rifle configuration.
Optical equipment should be fitted securely and checked periodically to ensure that mounting screws and interfaces remain correctly positioned.
Available Calibres
The official Weihrauch listing identifies several calibre options within the HW100 X family:
- .177 / 4.5 mm
- .20 / 5.0 mm
- .22 / 5.5 mm
Availability can vary according to country, distributor, model specification, and local regulations.
Handling and General Use
Balance, stock position, trigger control, and sight alignment all contribute to repeatable handling.
The lighter aluminium cylinder used on the X-series changes the weight distribution compared with some previous HW100 configurations. Weihrauch states that the standard-length X-series receives a greater weight reduction than the corresponding carbine configuration as a result of the updated cylinder design.
Meanwhile, the thumbhole stock, textured inserts, adjustable buttplate, and ambidextrous layout provide several contact and adjustment points that can be configured for controlled sporting use.
Maintenance and Storage
Routine maintenance should remain conservative.
External surfaces can be kept clean and dry, while the stock and exposed metalwork should be inspected periodically for dirt, moisture, or visible damage. The magazine should also be kept free from debris that could interfere with normal operation.
More importantly, internal regulator, valve, trigger, barrel, or high-pressure air-system work should be left to a qualified airgun technician.
During storage, the rifle should be secured against unauthorized access and kept separately from pellets where required by local law.
Responsible Ownership
The Weihrauch HW100X T Thumbhole Synthetic Black Adjustable is not a toy. It is a high-pressure pneumatic air rifle and should always be treated accordingly.
Users should confirm the laws governing air rifles in their country or region before possession or use. Safe handling practices, suitable backstops, appropriate eye protection, secure storage, and strict muzzle awareness should be maintained at all times.
Overall, this HW100 X configuration combines Weihrauch’s updated regulated PCP platform with a black synthetic thumbhole stock, adjustable buttplate, 250-bar aluminium cylinder, 14-shot magazine system, Biathlon-style lever, and two-stage match trigger. These characteristics define the technical layout of the model while retaining the established HW100 format in an updated X-series configuration.
Gamo Air Rifles, PCP Airguns, Pellet Pistols and Modern Airgun Systems
Choosing the right gamo air rifle depends on how the rifle will be used, the preferred caliber, the powerplant, and the shooter’s experience level. Gamo produces a broad range of recreational, target, and sporting airguns, so buyers searching for a gamo pellet gun, gamo air rifles, or a traditional gamo pellet rifle can compare several operating systems before deciding which configuration best fits their needs.
One of the most familiar designs is the break barrel air rifle. This platform remains popular because it combines straightforward operation with a self-contained powerplant. Shooters comparing high powered air rifles or a high power air rifle should consider much more than headline velocity. Pellet weight, caliber, barrel length, trigger quality, consistency, and shooting conditions all affect practical performance.
Models chambered as a gamo 177 configuration are frequently selected for target shooting and recreational use because .177 pellets generally offer a flatter trajectory than heavier calibers. Likewise, a gamo break barrel rifle provides the simplicity many shooters want without the need for a separate compressed-air charging system.

Calibres, FAC, Power, Scope and Accessories for the Weihrauch HW100X T Thumbhole Synthetic Black Adjustable
The Weihrauch HW100X T Thumbhole Synthetic Black Adjustable is available in several calibre configurations, allowing the rifle to be supplied in specifications appropriate for different markets and regulatory environments. According to Weihrauch, the current HW100 X platform is offered in .177, .20 and .22 calibre. Exact availability, muzzle-energy specification, and licensing status can vary substantially by country, so the specification of the individual rifle should always be checked before use.
.177 Calibre – 4.5 mm
The .177 calibre version uses 4.5 mm pellets and is one of the most widely encountered configurations for sporting air rifles.
Because pellet choice, rifle configuration, local energy limits, and manufacturer specification can all affect operation, users should select ammunition that is specifically suitable for the rifle rather than assuming that every .177 pellet will perform identically.
For organized target shooting, training, and general sporting use, .177 remains a commonly recognized calibre. The relatively broad availability of pellets also makes it practical from a maintenance and logistics perspective.
Before changing pellet weight or type, however, the rifle’s legal power classification should be confirmed.
.20 Calibre – 5.0 mm
The .20 calibre, or 5.0 mm option, occupies the middle position between .177 and .22.
Although it is less common in some markets, Weihrauch continues to list .20 among the calibre choices for the HW100 X series.
Owners considering this version should first confirm that suitable pellets are readily available in their region. Pellet availability can vary considerably compared with the more widespread .177 and .22 formats.
Because ammunition dimensions must match the rifle precisely, only correctly specified .20-calibre pellets should be used.
.22 Calibre – 5.5 mm
The .22 calibre, measuring approximately 5.5 mm, is another factory-listed configuration for the HW100 X platform.
As with the other calibres, the operating characteristics depend on the specific factory power level and the ammunition being used. Therefore, calibre alone should not be treated as an indication of the rifle’s legal classification or muzzle energy.
Users should check the markings, documentation, and distributor specifications supplied with their particular rifle.
FAC and Legal Power Classification
The term FAC is commonly used in the United Kingdom in connection with air rifles that exceed the legal threshold applicable to non-FAC air rifles.
However, licensing rules vary significantly from one jurisdiction to another. A rifle that is unrestricted or differently classified in one country may require a licence, permit, registration, or specific storage arrangements elsewhere.
For this reason, the Weihrauch HW100X T should not automatically be described as FAC or non-FAC without reference to the actual rifle specification and local law.
In the UK, purchasers should verify whether the individual rifle falls within the applicable non-FAC limit or whether a Firearm Certificate is required. In other countries, completely different thresholds and classifications may apply.
Local regulations should therefore be checked before purchase, possession, modification, transport, or use.
Power and PCP System
Rather than relying on a spring-powered mechanism, the HW100X T operates through a pre-charged pneumatic system.
Weihrauch specifies a 250-bar aluminium air cylinder for the current HW100 X generation. The rifle also includes an integrated pressure gauge and quick-fill system. In addition, the redesigned regulator is intended to provide improved consistency throughout the usable pressure range.
The company also states that the updated X-series provides at least a 50% increase in firing capacity compared with previous HW100 configurations, although actual shot count will depend on calibre, power specification, environmental conditions, and other variables.
Compressed-air filling should only be performed with equipment designed and rated for the required pressure.
Scope Mounting Options
The HW100 X platform can be supplied with either a Picatinny rail or an 11 mm prism mounting system, depending on the exact configuration.
Consequently, the most important factor when selecting a scope is compatibility with the rifle’s actual mounting rail.
A general-purpose air-rifle scope with clear optics, secure adjustment controls, and suitable eye relief can be used for sporting and target applications. Rather than choosing optics solely by maximum magnification, users should consider the distances at which the rifle will legally and safely be used.
Moderate magnification is usually easier to manage during routine target practice because a wider field of view can be maintained.
The mounting rings must correspond to the rail type fitted to the rifle. An 11 mm mount should not be confused with a Picatinny mount, as the two systems use different interfaces.
Useful Accessories
Several accessories can support safe ownership, transport, maintenance, and routine use of the HW100X T without altering its underlying performance.
Recommended practical accessories include:
- Protective rifle case for storage and transport
- Suitable eye protection for target and range use
- Pellet storage container to keep ammunition clean and organized
- Manufacturer-compatible fill adaptor
- Rated PCP charging hose
- Approved compressed-air cylinder or filling system
- Basic exterior cleaning cloth
- Airgun-compatible cleaning equipment
- Spare factory magazines where legally permitted
- Secure rifle cabinet or locking storage solution
- Correct Picatinny or 11 mm scope mounts
- Manufacturer-approved seals and service components
PCP Filling Equipment
Because the HW100X operates at pressures of up to 250 bar, charging equipment must be rated appropriately.
A suitable PCP filling arrangement may include a diving cylinder, compressor designed for PCP equipment, or another manufacturer-approved compressed-air source.
Connections, hoses, gauges, and adaptors should be inspected periodically for wear or damage. Oils and lubricants that are not specifically approved for high-pressure PCP systems should never be introduced into the charging system.
Final Configuration Considerations
The Weihrauch HW100X T Thumbhole Synthetic Black Adjustable combines three factory-listed calibres with a regulated 250-bar PCP platform, 14-shot magazine, adjustable stock arrangement, and interchangeable scope-mounting configurations.
When configuring the rifle, calibre, legal power category, mounting system, ammunition, charging equipment, and storage requirements should all be considered together.
Above all, the exact specification stamped on the individual rifle and the laws of the country where it will be possessed or used should take precedence over generalized online specifications.
Break-Barrel Rifles and Pistols
People researching the best air rifles frequently encounter spring-powered and gas-piston break-barrel platforms. Search terms such as brake barrel bb gun are also common, although pellet rifles and BB guns are technically different categories and may use different ammunition and barrel designs.
Compact airguns include the break barrel pellet pistol, break barrel air pistol, and break barrel pistol. Larger-caliber searches may include a 22 caliber break barrel air pistol, while buyers may also look for a break action pellet pistol, the best break barrel pellet pistol, or a 22 pellet pistol for recreational shooting.
Power-oriented shoppers sometimes search for the most powerful break barrel pellet gun. However, raw velocity should never be the only specification considered. Accuracy, appropriate ammunition, safe handling, and local laws are equally important. A phrase such as bee bee gun pistol may be used informally by shoppers, but users should confirm whether a particular handgun actually fires steel BBs, lead pellets, or another compatible projectile.
Gamo Swarm Multi-Shot Air Rifles
Gamo’s magazine-fed break-barrel systems have helped popularize multi-shot operation in a category that historically required a pellet to be loaded manually after every shot.
The gamo swarm magnum 10x gen3i is closely associated with this concept, while searches for the gamo swarm magnum, gamo swarm maxxim gen 3, and swarm magnum gen3i reflect interest in different Swarm generations and configurations. Another commonly researched model is the gamo swarm magnum pro 10x gen3i.
The broader gamo magnum gen3i category appeals to shooters who want high-energy break-barrel performance together with magazine-fed convenience. Gamo’s multi-shot technology is also frequently found through searches for gamo 10x, multi shot pellet gun, gamo swarm, gamo swarm 10x, and pellet gun with magazine.
A magazine system can make repeated target sessions more convenient because pellets can be prepared before shooting begins. Nevertheless, users should always verify magazine compatibility, pellet length, pellet diameter, and model generation before ordering replacements.
Gamo Arrow PCP Air Rifles
Shooters interested in pre-charged pneumatic technology may encounter the gamo arrow range. The gamo arrow pcp combines a PCP powerplant with a lightweight sporting format, while the full term gamo arrow pcp air rifle is commonly used when comparing it with conventional spring or gas-piston rifles.
Related searches include pcp arrow guns, arrow rifle, pcp arrow gun, arrow rifles, and arrow air rifle. These phrases generally reflect interest in compact PCP-style sporting rifles rather than traditional break-barrel platforms.
Caliber-specific buyers may search for a gamo arrow .22, while the gamo arrow classic may appeal to shooters looking for another Arrow-series configuration.
PCP technology uses stored compressed air rather than relying on a spring or piston being compressed for each shot. This can produce a smooth firing cycle, reduced mechanical movement, and consistent shot-to-shot performance when the rifle is properly filled and maintained.
Understanding PCP Airguns
A pcp air rifle uses a reservoir filled with high-pressure air. PCP stands for precharged pneumatic, and the technology is widely used in modern sporting and precision airguns.
Searches for pcp air rifles, pcp rifle, pcp guns, pcp rifles, and pcp air gun generally refer to this same basic operating principle. Some buyers describe the platform as an air rifle compressed air system, while others search for a pcp pellet rifle or use the reversed phrase rifle pcp.
PCP rifles usually require additional filling equipment such as a suitable hand pump, compressor, or certified high-pressure cylinder. Users should follow the manufacturer’s recommended fill pressure because overfilling a reservoir can be unsafe and may also reduce performance.
Gas-Piston and Lever-Operated Airguns
A common beginner question is what is a gas piston air rifle. Instead of using a traditional coiled steel spring, a gas-piston system compresses gas inside a sealed cylinder. When the trigger is released, the piston moves rapidly and compresses air behind the pellet.
Other mechanical airgun designs include under lever air rifles, the singular underlever air rifle, and the alternative spelling under lever air rifle. In these designs, a separate lever positioned beneath the barrel is used to cock the mechanism.
Shooters may also research a side lever air gun or side lever air rifle, where the cocking lever operates from the side of the receiver. These fixed-barrel layouts can provide a different shooting experience compared with conventional break-barrel systems.
Search terms such as lever action pellet gun, air gun thumb lever, and lever action air rifle can refer to several different mechanisms, so buyers should check the specific manufacturer’s action type rather than assuming every lever-operated airgun works identically.
Gamo Shadow and High-Velocity Searches
Long-running Gamo product lines continue to generate searches including gamo shadow 1000, shadow 1000 gamo, and gamo 1000 shadow. Another associated search phrase is 1000/4.5, which is often used by shoppers researching 4.5 mm or .177-class air rifles.
Velocity-focused buyers may also search for a gamo 1800 fps air rifle. Advertised velocity can vary according to pellet composition and weight, so actual shooting performance may differ when standard lead pellets are used.
Likewise, shoppers researching gamo 1800 fps air rifle price should compare the exact model number, caliber, powerplant, bundled optic, warranty, and regional specification rather than relying solely on a velocity figure.
Other unusual search terms such as shotgun pellet gun may describe an airgun with styling inspired by a shotgun rather than a conventional pellet rifle. Searches for pellet guns that can kill should be approached from a safety perspective: airguns are not toys, and even relatively modest-powered models can cause severe or fatal injuries. Every airgun should therefore be handled with the same disciplined muzzle and trigger control expected of potentially dangerous sporting equipment.
Air Pistols, Pellet Pistols and CO2 Systems
The air pistol category includes many different operating systems, and modern air pistols may use springs, gas pistons, CO2 cartridges, or pre-charged pneumatic reservoirs.
For pellet-firing handguns, common searches include pellet pistols, pellet pistol, pistol pellet gun, pellet handgun, pellet gun pistol, pellet gun pistols, pistol air, and air pellet pistol.
CO2-powered handguns form another major category. A co2 pistol typically uses a disposable carbon-dioxide cartridge to propel BBs or pellets. Buyers may also search for pistol co2, co2 pistols, or the commonly mistyped c02 pistol.
Related searches include co2 air pistols, co2 gun, c02 guns, guns co2, and co 2 gen. Regardless of spelling, the key consideration is ammunition compatibility and the correct cartridge type specified by the manufacturer.
CO2 performance can be affected by ambient temperature because pressure changes as the cartridge becomes warmer or colder. For that reason, shooters should expect some variation in velocity during different environmental conditions.

Target Shooting and 10-Meter Airgun Use
Precision shooting requires appropriate targets and a safe backstop. A 10m rifle is generally associated with structured 10-meter air-rifle shooting, where accuracy, repeatability, shooting position, and trigger control are emphasized.
Recreational shooters may use pellet gun targets, while rifle users commonly search for air rifle targets, targets for air rifle, and airgun targets. The term air gun targets is another broad variation covering both rifle and pistol applications.
Dedicated practice setups can include air rifle shooting targets and airgun shooting targets designed to provide clear aiming points and easy scoring. Depending on the shooting discipline, an air rifle target may use small scoring rings intended for precision practice.
Handgun shooters may choose air pistol targets, whereas a pellet rifle target should be paired with a backstop capable of safely containing the pellets used by the particular rifle.
Airgun Cleaning and Maintenance
Regular airgun maintenance helps preserve reliability, accuracy, and safe function. Although airguns generally require less bore cleaning than many powder-burning firearms, seals, external metalwork, fasteners, magazines, and moving components still need periodic inspection.
A pellet rifle cleaning kit can contain cleaning rods, pull-through systems, suitable patches, and other airgun-safe tools. Likewise, a pellet gun cleaning kit can help remove accumulated debris when cleaning is genuinely required.
Proper air gun maintenance also involves checking stock screws, inspecting seals, keeping optics securely mounted, and following the manufacturer’s lubrication guidance. Excessive oil should be avoided because unsuitable lubricants can damage seals or cause unwanted combustion inside some spring-piston airguns.
For PCP equipment, reservoir condition, fill fittings, O-rings, and pressure gauges should also be inspected periodically. Magazine-fed models should be kept clean so pellets feed smoothly without deformation.
Ultimately, the best choice depends on the intended use. A traditional break-barrel rifle offers simplicity, a Gamo Swarm platform adds multi-shot convenience, and a PCP system provides a smoother firing cycle with an external filling requirement. Comparing caliber, powerplant, ergonomics, ammunition, maintenance demands, and safe target equipment makes it much easier to select an airgun that delivers dependable performance for responsible recreational or target shooting.
