Lower Receivers and Components

BR-15 and BR-X Lower Receivers

Bison Armory carries a selection of forged and billet lower receivers for BR-15 (6.8 SPC) platform rifles. We carry only the Mega billet and monolithic billet receivers for BR-X (7.62 NATO) platform rifles.

 

BR-15 Forged Lower Receivers

The Bison Armory mil-spec forged lower receiver is compatible with any high-quality mil-spec forged upper receiver on the market. The receiver is perfectly finished with hard-coat anodizing to give it a deep black appearance. Caliber is marked Multi.
