With the new Short Locking Rail Panels by Weaver you can protect any of your unused rail lines. You can not only stave off damage to the rail lines but you can provide a gripping surface that shields you from the sharp rail edges and the heat from the weapon.

These new panels are made from a ridged polymer that incorporated the patented locking mechanism to ensure the rails always stay in place. This design fits almost all Picatinny spec rails and every rail panel can cover 1.6 inches.
