These stocks are made of the same fiber filled polypropylene as all of our black stocks. The dye has been changed in order to achieve the Olive Drab Green and the Less than Lethal Orange coloring. The bright Orange of our less than lethal firearm stock gives quick recognition for police officers. The Mark 6 was actually designed for Less than Lethal shot. The shell holder in the butt stock allows the user to see what type of shell he is choosing before removing the shell from the shell carrier. This saves time and helps to insure proper use of different shot shells. When fully loaded the Mark 6 stock carries 5 extra shells. The shell carriers can be individually adjusted to ensure a tight hold on the shot shell and accommodates all 12 gauge shells from 2-3/4″ to 3-1/2″ inches in length. Our forends only fit the Mossberg shotguns that have the steel tube in the center that the action bars are welded to. If your forend is held to the action bars by pins and there is no steel tube in the center of your forend when it is removed from the action then our forend will not fit your gun.
