The Black Rain Ordnance Spec-15 Sport Rifle 5.56 (brand part no. BRO-SPORT-CWG-OPT-MD) is a feature-rich AR platform finished in Cold War Grey and built for shooters who want a rifle that’s ready to run out of the box. Chambered in 5.56x45mm NATO with a 16-inch 4150 chromoly barrel and A2 flash hider, it runs a direct impingement gas system on a Spec 15 forged aluminum receiver set with a salt bath nitride-coated bolt carrier group for reliable, low-maintenance cycling. A Mil-Spec G.I. trigger keeps the fire control group familiar to any AR shooter, and a mounted ZeroTech optic means there’s no separate optic purchase or mounting needed. It’s built for range use, home defense, and shooters who want immediate out-of-box capability.
