The Black Rain Ordnance BROMLRBLK Lower Receiver Milled 7075-T6 Aluminum Black Anodized for AR-Platform is a precision-machined fire control group housing designed for tactical shooters and gunsmiths who demand uncompromising durability and accuracy. As the serialized foundation of any AR-pattern rifle, a high-quality lower receiver is essential for reliability and structural integrity.
This lower receiver is milled from aerospace-grade 7075-T6 aluminum, a material known for its superior hardness and fatigue resistance compared to standard 6061-T6 forgings. The T6 heat treatment ensures consistent grain structure, providing dimensional stability and resistance to deformation under sustained fire or mounting stress. The black anodized finish offers corrosion resistance and a professional appearance while minimizing light reflection.
Gunsmiths and competitive shooters will find this lower receiver compatible with various AR-platform builds, including those chambered in 5.56 NATO, 6.5 Creedmoor, and .300 Blackout. Its weight efficiency at 0.8 lbs ensures minimal system mass without sacrificing structural rigidity or dimensional tolerance, making it an excellent choice for precision builds.
