Wheeler Engineering DELTA SERIES AR MAINTENANCE MAT DARK GRAY 156824

Padded neoprene mat with rubber backing protects gun's finish during cleaning. Big enough to accommodate a full-size AR-15/M16 rifle. Features a big exploded drawing of an AR-15 organized by major groups - even a schematic of a disassembled 30-round magazine. Absorbs excessive oils and solvents and keeps your work surface dry and clean. Rolls up easily for storage.
