Make sure you’re prepared for whatever may come your way, and pick yourself up a spare 24 round magazine for your ASG B&T USW A1 and other compatible airsoft pistols. Although this magazine is designed for the B&T USW A1 blowback airsoft pistol, this magazine is backwards compatible with the CZ 75, CZ SP-01 Shadow, CZ ACCU Shadow, & CZ Shadow 2 airsoft pistols. Constructed fully from metal alloy, this spare magazine option can withstand high impact drops, and offers a more authentic weight to your lowdown. Green Gas or propane powers this airlift pistol, which is filled directly into the magazine. A high tension internal steel spring ensures rapid and smooth BB feeding from the magazine to the firing chamber, with less risk of jams.
