The Vapor X 308 Keymod Free Float Rail was designed to maximize ergonomics and comfort. The asymmetric profile along the rail axis offers the best possible heat dissipation while still maximizing weight savings. Unlike many other ultralight rail systems on the market, the oversize cutouts and KeyMod placement allows for an exceptionally lightweight AR-308 system, which turns the weapon platform into a very manageable package. The Vapor X 308 Rail features a non-indexing barrel nut and clamping system (FREELOK) that utilizes free floating tabs to secure the rail to the receiver. FREELOK provides both frictional and mechanical locking forces to create a rock-solid bond between the rail and barrel nut. This rail system is designed to be compatible with the HIGH PROFILE DPMS Style Aero Precision 308 upper receiver (Gen 1) and alike.
