For builders and shooters who demand a purpose-built foundation for a pistol-caliber AR platform, the right receiver set makes all the difference. A receiver that balances durability, ergonomic enhancements, and magazine compatibility can transform a parts pile into a reliable, competition-ready or duty-capable PCC.

Constructed from 7075-T6 billet aluminum and CNC-machined for tight tolerances, the AA-0940 pairs a slick-side, optics-ready flat-top upper with a lower that features an integrated last-round bolt hold open and a flared magwell for fast reloads.

Design and materials

The AA-0940 upper and lower are machined from 7075-T6 billet aluminum and finished in hard coat anodized black. The slick-side upper omits a forward assist and dust cover to reduce weight and simplify the exterior footprint — ideal for modern optics and short-barrel PCC layouts. At approximately 16.5 oz combined, the set keeps mass low while remaining robust under repeated use.
