Aero M5 Lower Receiver: The Foundation of Your Build
The Aero M5 lower receiver is the heart of your AR-15. It's the component that houses the trigger group, magazine well, and buffer tube. Key features often found on the Aero M5 lower include:

- Enhanced Features: Many models incorporate features like an integrated trigger guard, improving ergonomics and aesthetics.
- Compatibility: The M5 lower is designed to be compatible with a wide range of aftermarket parts and accessories.
Choosing the Right M5 Lower: Consider whether you prefer a stripped lower (requiring assembly) or a complete lower (including trigger group and other components). The choice depends on your experience level and preferred level of customization.
Aero M5 Upper Receiver: Completing the Assembly
The upper receiver houses the barrel, bolt carrier group, charging handle, and forward assist. The Aero M5 upper receiver shares the same commitment to quality and precision as the lower. Notable features often include:
