ASG B&T USW A1 — CO₂ Blowback PDW-Style Airsoft Pistol
The ASG B&T USW A1 is a faithful 1:1 airsoft replica of Brugger & Thomet’s USW A1, built as a compact PDW-style sidearm with real-world features for skirmishers and collectors. Out of the box it ships with a CO₂-powered 26‑round magazine for consistent, high-energy shots, while also offering compatibility with green gas mags for flexibility in the field. ActionSportGames+1
Thanks to its full-metal slide and metal-frame construction, the USW A1 delivers realistic weight and slide manipulation, including serrations and cocking wings for easier handling. A spring-assisted folding stock and non‑reciprocating optics rail greatly improve stability and aiming when you need to extend the pistol’s role into PDW territory. ActionSportGames+1
The pistol is a gas blowback design, so you get authentic recoil and cycle feel with each shot. With a threaded 14mm CCW outer barrel you can attach mock suppressors or tracer units, and the integrated 20mm rail accepts lights, lasers, and other accessories to tailor the pistol to your loadout. Typical velocity is around 328 FPS with 0.20 g BBs (approx. 1.0 J), giving it usable range and impact for its class. Evike+1
Whether you’re after realism for training, a compact primary for CQB scenarios, or a standout replica for your range bag, the ASG USW A1 balances durability, modularity, and performance in a unique package. BNT Online+1
