Angstadt Arms AA0940LRBA 0940 9mm Aluminum Black Anodized AR Pistol

The Angstadt Arms AA0940LRBA 0940 9mm Luger Aluminum Black Anodized Lower Receiver for AR-15 Handgun represents a precision-engineered solution for law enforcement, military, and civilian operators building compact 9mm AR pistols. This lower receiver is purpose-built for shooters who demand reliability and modularity in a pistol-caliber carbine platform, offering seamless integration with any mil-spec upper receiver to create a complete, functional firearm.

Machined from 7075-T6 billet aluminum and finished with a matte black hard-coat anodized coating, the AA0940LRBA delivers exceptional durability and corrosion resistance in field environments. The receiver incorporates a flared magwell for rapid magazine changes under stress, an integrated and oversized trigger guard that accommodates gloved operation, and a last-round bolt hold-open feature that locks the bolt to the rear when the final round fires—critical functionality for tactical reloads and administrative checks. The hard-coat anodize finish resists wear and provides a non-reflective surface ideal for low-light operations.

This lower receiver is ideal for AR pistol builds, compact home-defense platforms, and training configurations where 9mm ammunition cost-effectiveness matters. The mil-spec compatibility ensures you can source upper receivers and parts from proven manufacturers without fitment issues. Installation requires standard AR gunsmithing knowledge; the receiver accepts standard AR fire control groups and buffer systems. Law enforcement agencies evaluating PCC (pistol-caliber carbine) alternatives for duty or training will appreciate the robust construction and proven Angstadt Arms reputation for accuracy in the 9mm platform.
