Flexible ladder-style panel snaps securely into unused cross slots on Picatinny rails, protecting against dirt and dings and improving grip and weapon control. Prevents sharp rail edges from digging into your hand, snagging on clothing, and causing damage to gear, like cut and frayed slings or repelling ropes. Made of rubbery, slip-resistant Santoprene(TM) thermoplastic elastomer, the ultra-low-profile design keeps your handguard diameter slim. Covers 18 slots or can easily be trimmed to custom lengths and fitted between mounted accessories. To remove, simply pry up a corner and peel off. Manufactured by Falcon Industries. Mfg: Magpul SPECS: Santoprene rubber. 6-15/16" (17.6cm) long. Fits one side of standard carbine-length 1913 Picatinny rail.
