Angstadt Arms UDP-9 9MM Pistol w/ SBA3 Brace

Angstadt Arms UDP-9 Pistol

The Angstadt Arms UDP-9 SBA3 is a compact AR-15 style pistol chambered in 9mm Luger, set up with an SB Tactical SBA3 pistol brace. It feeds from GLOCK magazines, so if you already carry a Glock, the mags in your range bag will work here too.

Angstadt sweats the small stuff on this one. The bolt locks back on an empty magazine, the flared magwell helps you get the next mag in faster, and the oversized trigger guard leaves room for gloved fingers. The upper and lower are machined from 7075-T6 billet aluminum. The slick-side upper has a properly sized ejection port and skips the forward assist and dust cover, which a 9mm doesn’t need. It runs a mil-spec AR-15/M4 fire control group and works with most aftermarket 9mm PCC triggers if you want to upgrade later.

Up front is a 6″ chrome moly barrel with a 1:10 twist, black melonite finish, and an A2-style flash suppressor. The muzzle is threaded 1/2×28, so it’s ready for a suppressor when you are.
