ATI Outdoors SMC1100 Shotgun Magazine Clamp - 12 Gauge, DuPont Zytel Polymer, Black

The ATI Outdoors SMC1100 shotgun magazine clamp brings real utility to your 12 gauge setup. This DuPont Zytel polymer clamp locks down magazine extensions to your barrel with solid mechanical support, eliminating the flex and rattle that loose extensions can introduce. Whether you're running an extended tube for waterfowl, upland hunting, or tactical work, a secure mag-to-barrel connection matters—it keeps things reliable when it counts. The clamp works on any 12 gauge shotgun, making it a universal upgrade worth keeping in your kit.

Beyond magazine duty, the SMC1100 doubles as a mounting platform. The integrated 1-inch diameter mount accepts lights and lasers, giving you flexibility to add an accessory light or laser without permanent modifications. The reversible sling swivel stud works for both right and left-handed shooters, so you're not locked into one setup. Installation is straightforward, and the tough black polymer resists corrosion and wear in field conditions.

This is the kind of practical accessory that doesn't grab headlines but earns its place on serious shotguns. A reinforced magazine connection, a light mount, and ambidextrous hardware in one piece—all in a material that handles weather and hard use without fuss.
