Built as a complete lower for a custom .308 AR setup, this Aero Precision M5 receiver gives hunters and shooters a solid starting point when assembling a big-bore rifle around standard AR .308 components and magazines. It ships without a stock, leaving that choice open for the final fit and intended use. The integrated trigger guard, threaded rear takedown pin detent hole, and screw-pin bolt catch are practical details that support a cleaner, more streamlined build. It also accommodates standard selectors, including 45-, 60-, and 90-degree options, and is designed to work with aftermarket pistol grips without a gap.
