Angstadt Arms AA-0940 9mm AR Pistol – Custom Upgrades, Ambidextrous Controls, Threaded 1/2-28 Barrel
This Angstadt Arms AA-0940 blends the company’s billet AR-9 receiver set with a full suite of premium aftermarket components. Factory-engineered last-round bolt hold-open for Glock magazines, a slick-side upper, and a continuous top rail give the pistol an efficient, competition-ready foundation. Thoughtful upgrades—from the Geissele Super Charging Handle to the SB Tactical SBA3 brace—add measurable advantages without unnecessary weight.

What’s Included
- One Glock OEM polymer 33-round 9 mm magazine
The billet 7075-T6 receivers are black hard-coat anodized and marked “CALIBER: MULTI,” allowing barrel and bolt swaps to .40 S&W or .357 SIG if desired. Angstadt’s extended magazine-release paddle speeds reloads while retaining compatibility with standard Glock-pattern magazines.
Ambidextrous controls are a standout feature. The Geissele Super Charging Handle (DDC) offers positive purchase from either side, and the Radian Talon 45°/90° safety selector with FDE lever lets the shooter choose a short or standard throw. Battle Arms enhanced takedown and pivot pins simplify field-stripping.
A Velocity Precision Engineering straight-bow PCC trigger delivers a crisp, 4-pound single-stage break for fast follow-up shots. The direct-blowback action is tuned for reliability with 9 mm ammunition, and the Griffin Armament 3-lug quick-detach adapter on the 1/2-28 threaded muzzle is ready for compatible suppressors.
Ergonomics are rounded out by a free-float M-LOK aluminum handguard, a Daniel Defense textured polymer grip, and an SB Tactical SBA3 five-position adjustable brace. The result is a compact, controllable platform suited to competition, range work, or personal defense.
