The Cloud Defensive Cloud Optimized Rail was designed specifically for use with the OWL and is changing the way lights and handguards interact with each other. The CORv1 free float handguard features a recessed rail section that is nearly the same dimensions as the OWL control switch to keep it low profile and out of your field of view while also improving ergonomics. Additionally, the CORv1 is compatible with other popular lights and switches like the Surefire ST-07. The AR-15 handguard is machined from 6061-T6 aluminum and hardcoat anodized black to Mil-Spec standards. At 9.55”, it is great for 10.5” barrels with either a carbine or pistol length gas system. The 1.33” internal diameter is compatible with low profile gas blocks and is extremely slim for a comfortable grip and easy access to the light switch. The Cloud Optimized Rail is an innovative new way to build out a rifle with function and ergonomics in mind.
