The Angstadt Arms UDP9 is a 9mm personal defense weapon featuring a billet aluminum receiver set, flared magwell, integrated trigger guard and many other features. The UDP9 uses standard Glock 9mm magazines with last round hold open, and a flared magazine for faster reloads.


The 9mm bolt assembly in the Angstadt Arms UDP9 functions with a standard AR-15 fire control group, allowing for trigger customization. The 6" chrome moly barrel has a 1/10 twist is threaded for easy suppressor installation. Unlike many other factory SBRs, the UDP9 wears a Magpul MOE stock, K2 pistol grip, and ODIN Works 5.5" quad rail.
