Aero Precision M5 AR10 Stripped 7.62 NATO Stripped lower receiver Rifle

The Aero Precision M5 AR10 stripped lower receiver in 7.62 NATO is the foundation component for building a precision rifle platform trusted by military armorers, law enforcement marksmen, and civilian long-range shooters. This stripped lower represents the regulated firearm component—the serialized frame that defines legal ownership—allowing builders to customize caliber, barrel length, and optics configuration to match specific mission profiles or hunting applications. Aero Precision's M5 platform has become the industry standard for .308 Winchester and 7.62 NATO builds due to its dimensional accuracy and compatibility with aftermarket components across the AR-10 ecosystem.

Machined from aluminum forgings with tight tolerances, the M5 lower receiver features hardcoat anodized finish that resists corrosion and wear during field use and maintenance cycles. The receiver geometry accommodates standard AR-platform trigger groups, buffer tubes, and fire control components, while the magazine well is optimized for reliable feeding of .308 magazines—critical for sustained accuracy in precision shooting applications. At 0.94 pounds, the stripped lower provides a lightweight platform component that won't compromise overall rifle balance when paired with precision barrels and optic systems.

Builders completing this rifle will benefit from Aero Precision's reputation for quality control and dimensional consistency—factors that directly impact zero retention and group repeatability. The M5 lower integrates seamlessly with Aero Precision upper receivers and compatible third-party AR-10 components, enabling modular configurations for duty, competition, or precision hunting roles. FFL transfer and background check required at point of sale; assembly requires gunsmithing knowledge or professional completion work to ensure proper headspace and function.
