Accessories for Mossberg

Mossberg makes the 500 and 590 pump action families, as well as the JM 930 and JM 940 semi automatics built for three gun competition, the budget Maverick 88 pump, and the MC1 and MC2 compact pistols. Our Mossberg range covers two things: a stock that fits the shooter, and a red dot.

TST adjustable stocks

Two TST stocks exist, one shared by the JM 930 and JM 940 and one for the Maverick 88. Set once to your body, they bring the gun up to the same place on your shoulder and face every time. Its side plates and sling cups can be swapped to suit a left or right handed shooter. They are drop in replacements, made in Italy: Stocks for Mossberg.

Red dot mounts for shotguns

One Outer Impact mount covers six shotguns, from the 500 and 535 to the 590, 835, 930 and 935, in type C, which seats RMR, RTS and Docter pattern optics. A small red dot on a shotgun gives a fast aiming point for slugs and for shooters who struggle with a bead. It also lets you keep both eyes open and see the next target while you aim. Fit the optic, then zero it at the distance you shoot slugs most often.

Red dot mounts for MC1 and MC2 pistols

The compact MC1 and MC2 pistols, in their c and sc versions, have their own type C mount in the rear sight slot; the slide is not cut. Both mounts are in Red dot mounts for Mossberg.

Many models, one page each

Because Mossberg's model numbers overlap, each model has its own page in the menu under By model, from the 500 to the MC2, with only the parts that fit it.
