Weihrauch HW100 Bullpup Full Length .177 Air Rifle

Weihrauch HW100 BP – Precision Bullpup Performance, Without Compromise

The HW100 BP brings the celebrated Weihrauch HW100 action into a compact bullpup format, merging full-size power with superior balance and manoeuvrability. At just 83 cm long and weighing around 3.7–3.8 kg, it remains steady and agile—a perfect blend of accuracy and portability  .

Core Features That Set It Apart:

• Action & Magazine: Side-lever cocking paired with a reliable 14-round rotary magazine; mag swaps are intuitive and fast.
• Trigger: Weihrauch’s two-stage match-grade Rekord trigger is fully adjustable, offering an exceptional crisp break.
• Stock Design: Black ambidextrous soft-touch stock (beech wood base), with a height-adjustable rubber butt pad and ergonomic pistol grip shared with the HW44.
• Barrel & Silencing: 41 cm match-grade barrel (full model) threaded to accept a Weihrauch silencer, which delivers whisper-quiet performance.
• Capacity & Fill: Air cylinder holds 200 bar, yielding roughly 110 shots in .177 and 140 in .22 calibres (full model).
• Ambidextrous Ergonomics: Left/right hand operation for safety and lever; cheekpiece and grip fully versatile.
• Scope Mounting: Elevated Picatinny rail with minimal scope‑to‑barrel offset (≈30 mm), while underneath remains a 11 mm dovetail; also includes a fore-end rail.
