- Material: Most are made from 7075-T6 aluminum for strength and durability.
- Forging Process: The forging method affects strength and consistency. A well-forged receiver will have superior structural integrity.
- Finish: Finishes like hardcoat anodizing provide corrosion resistance and enhance durability.
- Compatibility: Ensure compatibility with your lower receiver and other components. Mil-Spec is generally preferred for broad compatibility.
