Weaver's Locking Rail Panels are designed to protect unused rail areas from damage while offering a gripping surface that shields operators from weapon heat and sharp rail edges. Constructed from durable, ridged polymer, these panels utilize the patented Rail-Lok integral locking mechanism to ensure they remain securely in place. Their low-profile design enhances feel and weapon control, making them an excellent addition to your firearm setup. Sold in sets of two, these panels are ideal for covering small uncovered rail sections adjacent to mounted accessories. The medium version provides full coverage for SCAR 3 and 9 o'clock rails, ensuring both protection and functionality.
