The MTM maintenance center, PMC-1, is constructed of a heavy gauge plastic with two removable, soft but sturdy rubber cradles. The tray has two sections that have sliding covers for storage of cleaning supplies and an open center section. Excellent for cleaning and general gun work. The MTM accessory box, PMC-2, is a large storage box for reloading supplies and other shooting accessories such as brass, shotgun shells, reloading equipment, etc. It is designed so the portable maintenance center stacks on top with the box handle accessible through the tray. PMC-1 available in red and PMC-2 in black.
