More capacity, more time on target
The ASG B&T USW A1 50rd Gas Magazine takes your gas gun to the next level. With a 50-round capacity it more than doubles the older 24 and 26-round mags, meaning fewer reloads and more time keeping your head in the game during a fast-moving skirmish or an IPSC-style shooting session.
Wide platform compatibility
Designed for the ASG B&T USW A1, this magazine is also fully compatible with the ASG CZ 75, CZ SP-01 Shadow, CZ ACCU Shadow and CZ Shadow 2 gas blowback pistols. One spare mag covers a whole family of popular sidearms.
Built for reliable performance
Full-metal construction gives the magazine a realistic weight and the durability to survive repeated drops and hard reloads. Charged with green gas it delivers consistent blowback and feed, and ASG recommends its own Ultrair Power Gas for the best results.
The essential spare
Every gas pistol shooter benefits from a spare magazine ready to go, so you can reload in seconds and stay in the fight. Stock up on BBs and gas and browse more airsoft accessories at Platoon Stores. Gas and BBs sold separately.
