GunTec M-LOK Rubber Insert Covers Features The GunTec M-LOK Rubber Insert Covers are molded from soft neoprene rubber and sized to slide snugly into any unused M-LOK slot on a compatible handguard or rail. Leaving slots uncovered allows dirt mud and debris to build up inside the rail body over time so these inserts keep the handguard clean and functioning as intended. The Gen 2 design adds small protruding grooves across the surface of each insert giving fingers something to grab onto when it is time to remove a cover and mount an accessory. This small detail makes swapping gear in the field faster and less frustrating than smooth featureless covers. Each kit includes 10 pieces enough to cover a full handguard or to keep a supply on hand for multiple rifles. Because the inserts are made from rubber rather than rigid polymer they flex slightly for an easier more secure fit inside the M-LOK slot without rattling loose during normal use. Made in the USA these covers are a simple and inexpensive way to finish the look of an M-LOK handguard while protecting it from the elements. They are a practical addition for any builder who wants a clean debris-free rail until additional accessories are added.
