Blackhawk's Locking Rail Panel protects unused rail areas from damage while providing a gripping surface that shields the operator from weapon heat and sharp rail edges. Made of a tough, ridged polymer and using the patented Rail-Lok integral locking mechanism to keep them securely in place, these low-profile rail panels improve feel and weapon control. Sold in sets of two, these panels are perfect for use on those small uncovered rail areas next to mounted accessories. Fits most Picatinny-spec rails. Covers 1.6" of rail.
