The EPC-9 forged receivers are 7075-T6 aluminum with a Type III hardcoat anodized finish, displaying Aero logos and rollmarked "AERO PRECISION / LAKEWOOD, WA." The lower is marked "MOD EPC-9 / CAL MULTI" with selector pictogram markings. The upper is a slick-side EPC-9 configuration with no forward assist and no dust cover, and it incorporates an integrated last-round bolt hold open system.
A Rosco 5 inch 4150 steel barrel with a 1:10 twist anchors the 9mm blowback action. The bolt is marked "FM," and the platform is designed for Glock-pattern, double-stack 9mm magazines. Country of origin is the United States.
Controls and handling are enhanced by a Radian Raptor ambidextrous charging handle and a right-side bolt release lever. A flat-faced trigger provides a modern, straight-pull profile. The Hogue overmolded rubber grip and SB Tactical adjustable pistol stabilizing brace with strap add secure, adaptable ergonomics.
The free-float aluminum M-LOK handguard includes a continuous top Picatinny rail for uninterrupted mounting space and an integral QD sling socket. The handguard keeps weight forward minimal while preserving rigidity around the Rosco barrel.
