Aero Precision EPC-9

The Aero Precision EPC-9 lower receiver is the purpose-built foundation for a 9mm pistol caliber carbine (PCC) build. Machined from forged 7075-T6 aluminum with Type III hard coat anodize, it is designed from the ground up to accept standard-frame Glock G17/G19-pattern magazines, eliminating the need for adapters or feeding compromises. The integrated, enlarged trigger guard eliminates the weak point of a pinned guard, and the flared magwell makes reloads faster under pressure.

Unlike converted AR lowers, the EPC-9 uses a dedicated blowback-optimized receiver set engineered specifically for pistol-caliber operation. The last-round bolt hold-open feature (when paired with the EPC-9 upper) is a critical reliability improvement over generic 9mm AR conversions. At the $175 price point, this stripped lower represents an exceptional entry into a dedicated PCC build, ready to accept any mil-spec fire control group and a wide variety of stocks, braces, and buffer systems.
