The Black Rain Ordnance Spec-15 Sport Rifle (Black Rain Ordnance part no. BRO-SPORT-BBRNZ-OPT) is a feature-rich 5.56 NATO AR platform finished in Burnt Bronze and built for performance, durability, and versatility. A 16-inch 4150 chromoly barrel pairs with an A2 flash hider and a direct impingement gas system running a .750 low-profile, non-adjustable gas block for proven, simple operation. The forged aluminum Spec-15 receiver set and salt bath nitride-coated bolt carrier group keep the rifle cycling reliably, while a mil-spec G.I. trigger delivers a familiar break. This model ships with a Vortex optic already mounted, so it’s ready for the range or duty use straight out of the box.
