The AA-0940 features billet-style upper and lower receivers with an integral brass deflector and streamlined exterior that omits a forward assist and ejection-port cover. The receiver carries a full-length Picatinny rail for mounting, and the handguard adds M-LOK slots at 3, 6, and 9 o'clock plus a short top rail segment near the muzzle.
The 10.5" 9mm barrel is threaded and capped with a multi-port, fluted cylindrical muzzle device. Barrel markings include 9mm Luger with the Angstadt chevron logo. The platform uses a simple blowback action and a push-button magazine release, with a manual safety selector.
Ergonomics include an SB Tactical adjustable stabilizing brace with a hook-and-loop strap on a carbine-style buffer tube, along with a rubberized finger-groove pistol grip. The matte black aluminum construction keeps the package durable and consistent in finish.
This pistol is designed for Glock double-stack 9mm magazines and ships with three 33-round OEM examples for a 33+1 capacity. Receiver markings include ANGSTADT ARMS LLC, CHARLOTTE NC, USA and roll marks for MODEL: AA-0940 and CALIBER: MULTI.
