Aero Precision M5 AR-10 Stripped Lower Receiver Black

Aero Precision's M5 .308 Stripped Lower Receiver represents the foundation of a robust, reliable big-bore AR platform. Crafted with precision and adhering to mil-spec dimensions, this lower receiver ensures seamless integration with standard AR 308 components and magazines.

Constructed from high-grade 7075-T6 forged aluminum, the M5 is both durable and lightweight at just 12 ounces. The anodized black finish provides not only an aesthetically pleasing appearance but also superior resistance to wear and corrosion.

One of the standout features of this stripped lower is its upper tension screw system. This allows you to fine-tune the fit between your upper and lower receivers using a nylon-tipped tensioning set screw located in the grip tang area. Such attention to detail results in enhanced stability and accuracy during operation.

The design includes a threaded rear takedown pin detent hole for easy assembly using a 4-40 set screw, eliminating potential frustrations commonly associated with roll pins. Furthermore, Aero Precision has integrated an innovative bolt catch setup that utilizes a screw pin instead of traditional roll pins.

An integrated trigger guard adds strength while reducing weight, showcasing Aero Precision’s commitment to functional excellence without unnecessary complexity. Selector markings on the receiver are compatible with various safety selector configurations—45-degree, 60-degree or standard 90-degree options—offering flexibility according to user preference. It even accepts Battle Arms Development short throw safety selectors if desired.

This piece exemplifies American craftsmanship as it's proudly made in America—a testament to quality control standards that firearms enthusiasts can trust implicitly when building their next rifle project from scratch.
