AeroPrecision
Building an AR-308 platform rifle starts with a quality lower receiver assembly, and the Aero Precision M5 Lower Parts Kit with MOE Grip gives you the right foundation without the guesswork. This kit handles the mechanical grunt work of lower assembly—all the springs, detents, pins, and levers you need—so you can focus on the parts that matter most to your setup. Since it ships without a fire control group, you're free to choose your own trigger, whether that's a competition match, a precision long-range unit, or a smooth hunting trigger. That flexibility is why experienced builders reach for this kit.
The kit is purpose-built for the M5 platform, which means you get M5-specific takedown and pivot pins, bolt catch, and magazine catch components engineered to work together without modification. The included Magpul MOE Grip in black offers proven ergonomics and a clean aesthetic that pairs well with any stock or furniture choice. Every spring, detent, and roll pin you need is in the box—no hunting through parts bins or ordering separately.
Whether you're assembling a precision rifle, a tactical build, or a hunting AR-308, starting with a complete, matched lower parts kit cuts assembly time and eliminates the risk of mixing incompatible components. This is the kind of detail that separates a solid build from a headache.
