Design and Construction

The ANGSTADT ARMS AA-0940 is a precision-machined receiver set milled from 7075-T6 billet aluminum and finished with a hard coat anodized black. At roughly 16.5 oz combined for upper and lower, it provides a lightweight but rigid foundation for pistol-caliber builds. CNC tolerances ensure repeatable fitment with AR-15 compatible components and long-term durability under hard use.

Upper and Lower Features

The flat-top upper is optics-ready and features a slick-side profile—no forward assist or dust cover—which simplifies the layout for modern sighting systems. The lower includes practical enhancements for PCC work: an integrated last-round bolt hold open and a flared magwell to speed reloads during competition or high-tempo drills.

Caliber and Magazine Compatibility

Designed to feed from GLOCK(R)-pattern magazines, this receiver set supports 9mm, .40 S&W, and .357 SIG, making it a versatile choice for shooters who prefer common PCC calibers. The AA-0940 is intended for blowback operating systems and accepts standard AR-15 triggers, safeties, and buffer components, allowing broad customization for weight, recoil impulse, and ergonomics.

Applications and Build Notes

For competition shooters, the flared magwell and Glock-mag compatibility accelerate reloads and magazine management. For personal defense or tactical uses, the rigid billet construction and optics-ready top rail support durable, minimized builds. Note that barrels, stocks, and buffer systems are sold separately; this listing covers the receiver set only. The listed price is $1,100.99—reflecting billet construction and integrated machining work.

For builders seeking a modern, billet 9mm AR foundation that accepts GLOCK(R) magazines and standard AR-15 parts, the ANGSTADT ARMS AA-0940 is purpose-built. Check current availability and purchase options directly on the product page: Check current availability.
