Aero Precision M5 AR-10 Lower Receiver with MOE Grip and STR Stock - Complete Lower

The Aero Precision M5 Complete AR-10 Lower Receiver is a .308 Win lower with parts installed at the factory, built on the M5 enhanced forging for standard AR-308 components and magazines.

Features:

• Enhanced M5 forging machined from 7075-T6 aluminum
• Works with standard AR-308 components and magazines
• Magpul MOE grip installed
• Magpul STR stock installed
• Lower parts kit and .308 carbine buffer and spring installed
• Rear takedown pin detent hole threaded for a 4-40 set screw
• Bolt catch threaded for a screw pin, so no roll pin is needed
• Integrated trigger guard and upper tension screw

The M5 lower is Aero Precision's big-bore AR design for .308 Win and similar cartridges. The enhanced forging uses custom takedown and pivot pins and an extended magazine catch button, the selector markings work with 45, 60, or 90 degree safety selectors, and there is no gap with aftermarket pistol grips.

Every included part is installed at the factory, so the lower is ready for an upper receiver once it ships to your FFL. The Magpul STR carbine stock drops onto the carbine receiver extension supplied on this lower.

This version has a black anodized finish.

Aero Precision applies manufacturing standards drawn from its aerospace background to every handguard, receiver, and small part it builds, giving shooters components that fit together the way a factory rifle would rather than requiring extra fitting at the bench.
