The MAC 2 3-Gun 12 gauge shotgun (MAC part no. 21000156) is an inertia-operated semi-auto from Military Armament Corporation, offered through Military Arms. A 21-inch barrel gives a longer sight radius and a smooth swing, and the black synthetic furniture is built to stand up to field and range use. A fiber optic front sight makes the bead easy to pick up, which helps on moving targets and in poor light. It suits shooters who want an affordable semi-auto for sporting clays, 3-gun style practice and general use.

Key Specifications

• The gauge is 12, which has the widest range of loads available for any shotgun.
