Weihrauch HW100X Karbine Synthetic Thumbhole PCP Air Rifle

1,050.00

The HW100X Karbine Synthetic takes everything people already liked about the HW100 platform and quietly improves the parts that actually matter. Same smooth side lever, same reliable rotary magazine system, same excellent Weihrauch trigger, just with better efficiency, lower weight, and a much more usable shot count.

 

This synthetic thumbhole version leans heavily into practicality. Less polished cabinet-piece energy, more “lives in the truck and gets used properly” energy.

 

Key Features

  • Ultra-efficient regulated PCP system
  • Lightweight aluminium air cylinder
  • Spring-assisted side lever action
  • Weihrauch rotary magazine system
  • Synthetic thumbhole stock
  • Picatinny + dovetail optic rail
  • Weihrauch moderator included
  • Ambidextrous safety system
  • Karbine length for improved handling and storage

 

Performance / Use Case

The HW100X still feels unmistakably like a HW100, calm, consistent, and slightly over-engineered in the best possible way.

 

The updated regulator and valve setup massively improve efficiency over older models, giving extremely consistent shot delivery and significantly more usable shots per fill. In .177, you’re looking at around 210 shots from a 250 BAR fill, which is frankly slightly ridiculous considering how well behaved the rifle remains throughout the string.

 

The Karbine layout makes a genuine difference in handling as well. It’s easier to move around with, easier to store in vehicles or cabinets, and generally more practical without losing the steady shooting characteristics that made the platform popular in the first place.

 

Synthetic Thumbhole Stock

The synthetic thumbhole stock is built around function rather than trying to impress people with walnut grain.

 

The thumbhole layout naturally positions the hand more vertically, which reduces wrist strain and helps support the rifle’s weight more comfortably during longer sessions or rested shooting. Combined with the textured synthetic finish, it gives the rifle a secure, planted feel in poor weather or rougher field use.

 

This is the version for shooters who actually use their rifles rather than gently polishing them between cups of tea.

 

Practical Modernisation

Weihrauch has been fairly restrained with the updates, which honestly suits the platform.

 

The Picatinny rail addition is one of the more sensible changes, making scope mounting easier compared to the older dovetail-only setup while still retaining dovetail compatibility.

 

The included Weihrauch moderator remains one of the better factory silencers available and keeps the rifle impressively quiet straight out of the box.

 

Ambidextrous safety levers on both sides also keep operation simple regardless of shooting position.

The HW100X Karbine Synthetic is essentially Weihrauch refining an already very proven formula rather than trying to reinvent it.

 

It’s lighter, more efficient, easier to live with, and more practical than older HW100 variants while still keeping the calm, dependable feel that made the platform so respected in the first place.

If you want a modern regulated PCP that doesn’t feel overly tactical or gimmicky, but still quietly performs at a very high level, this does exactly that.
