Angstadt Arms UDP-9 9mm 16" 16-Round Threaded Barrel Rifle

The Angstadt Arms UDP-9 9mm 16" 16-Round Threaded Barrel Rifle delivers modern carbine performance in a compact, purpose-built platform designed for tactical professionals and serious civilian shooters. Built on proven blowback operating principles, this rifle bridges the gap between pistol-caliber carbines and full-size duty weapons, offering shooters a lightweight, maneuverable platform suitable for home defense, close-quarters training, or dynamic shooting disciplines.

The 16-inch barrel provides velocity optimization for 9mm while maintaining a profile light enough for extended tactical operations or vehicle-mounted use. The threaded barrel, with a pitch of 1/2x28 TPI, accommodates suppressors, muzzle brakes, or flash hiders, allowing operators to tailor muzzle signature and recoil management to mission requirements. At 8.2 pounds unloaded, the UDP-9 maintains manageable mass without sacrificing control during rapid fire or precision shooting.

The 16-round magazine capacity leverages affordable, widely available 9mm ammunition while the rifle's compact 34.2-inch overall length ensures mobility through tight entries and vehicles—critical for law enforcement, military training, or civilian home-defense scenarios where space and speed matter. The blowback action delivers inherent reliability with minimal moving parts, reducing maintenance demands in the field. This platform excels for operators prioritizing ammunition commonality with duty pistols, lower recoil impulse for accurate follow-up shots, and versatility in various tactical situations.
