The Angstadt Arms UDP-9 9MM 6" SBR is a compact pistol-caliber rifle built around a precision-machined 7075-T6 billet aluminum receiver set. Its straight blowback action, 6" chrome moly black melonite threaded barrel, and ultra light 5.5" M-LOK handguard create a smooth-shooting platform that stays controllable and reliable while accepting Glock-pattern magazines.

This short barrel rifle is well suited for range use, training, and PCC-style competition where a lightweight, maneuverable carbine shines. The B5 Systems Bravo stock and pistol grip support comfortable handling, while the Radian Raptor LT charging handle and Talon ambidextrous safety make operation intuitive for a wide range of shooters. Backed by Angstadt Arms’ focus on craftsmanship and innovation in pistol caliber carbines, the UDP-9 delivers a refined, modern AR-9 experience.
