Aero Precision
Serialized Aero M5 lower for a DPMS Gen 1 / SR-25 magazine build, with M5-specific receiver controls and pins.

Aero's forged M5 lower is the serialized anchor for this custom large-frame build path. Its SR-25-pattern magazine well and AR fire-control pocket preserve familiar controls, while the receiver geometry stays in the Aero M5 / DPMS Gen 1 lane rather than claiming universal AR-10 interchangeability.
The lower needs M5-specific pivot and takedown pins, bolt catch, and extended magazine-catch hardware. Choose the matching M5 lower-parts kit and a complete .308 recoil system before treating the lower assembly as complete.
Add the Aero Precision M5 Stripped Lower Receiver to your build and see how it enhances your platform.
