Machined from lightweight 6061-T6 billet aluminum, this receiver is finished with a heavy-duty Type III hardcoat anodized coating that resists wear and corrosion through regular use. The slick side profile omits standard ejection port hardware for a clean look suited to pistol caliber builds, while the billet construction holds tighter tolerances than a cast or forged equivalent.

The receiver is dimpled to work with anti-rotation handguards and is compatible with GLOCK-style magazine-fed lowers, supporting pistol calibers up to .45 ACP for a wide range of PCC configurations. It ships stripped, giving builders the flexibility to select their own bolt carrier group and internal components.

Expo Arms manufactures AR-15 components in the USA with attention to precise machining across its billet product line, aiming to give builders dependable, purpose-specific parts.
