These URGI Rail Panels from Geissele Automatics are 2-inch M-Lok panels finished in black, matching the type used on the military URGI (Upper Receiver Group Improved) upper. Rail panels snap into open M-Lok slots to give a smooth, comfortable gripping surface and protect the hand from an otherwise exposed handguard slot edge (Geissele Automatics part no. 04-428B).
