Angstadt Arms UDP-9 SBR 9mm 6" 17-Round Short Barrel Rifle

The Angstadt Arms UDP-9 SBR is a semi-automatic AR-pattern short barreled rifle chambered in 9mm Luger, built on the AR-15 platform. It is designed for shooters who want a compact, lightweight rifle that runs on inexpensive 9mm ammunition and Glock-pattern magazines.

The rifle has a 6-inch barrel with an A2-style flash hider and 1/2x28 threads for suppressor attachment. The upper and lower receivers are 7075-T6 billet aluminum with an anodized black finish. It includes a 5.5-inch free-float M-LOK handguard, a B5 Systems Bravo stock and pistol grip, a flared magwell, an oversized trigger guard, and a last-round bolt hold-open. A 17-round capacity magazine is included.

The bolt assembly is a 9mm bolt for a standard AR-15 hammer, and the rifle uses a manual safety.
