The BRO-SPEC-SERIES rifles feature the Black Rain forged receiver set, chromoly barrel chambered in 5.56mm, and a black nitride coated bolt and carrier group marked with Black Rain’s distinctive bio-hazard logo. Because the cost of manufacturing is significantly lower than producing their billet line consumers can get into a BRO-SPEC-Series for as little as $899.00 and still have confidence in a product backed by Black Rain’s excellent customer service.
