BLACKHAWK!"s Short 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.
