Adapter-mount accessories are designed to be attached to telescoping stock adapter accessory mount points. These are also compatible with Mesa Tactical Barrel Clamps and Magazine clamps. Adapter Mount Picatinny Rails fasten to the accessory mount points on the sides of Mesa Tactical High-tube telescoping stock adapters, not on the shotgun receiver.

Can be used on the sides of Mesa Tactical Barrel Clamps, Magazine Clamps and clamps used as front mount points for Mesa Tactical 20 inch and 24 inch rails, which feature the same mounting hole pattern as Mesa Tactical stock adapters.

Can be used on Mesa Tactical Picatinny rails for the Kel-Tec KSG shotgun.
