Meta Tactical Llc 90800 Mesa Mag Clamp Rem 12Ga
The Meta Tactical Mesa Mag Clamp for Remington 12-gauge shotguns is a no-nonsense aluminum accessory that locks your barrel and extended magazine tube into one solid, vibration-free unit. Built for shooters who demand a stable platform—whether you're running a tactical light, setting up for competition, or maximizing reliability on an extended-tube scatter gun—this clamp transforms a loose assembly into something you can count on at the range or in the field.
The clamp's dual-function design lets you mount a 1-inch diameter tactical flashlight on one side while clamping the barrel or magazine tube on the other, giving you true hands-free illumination without the cost of a dedicated rail system. Two hardened steel Allen head screws deliver a rock-solid grip that won't creep under recoil or prolonged use. Both sides feature standard pushbutton sling swivel sockets, so you can run it exactly how your setup demands.
Weighing next to nothing and built from durable aluminum, the Mesa Mag Clamp is engineered for the 12-gauge platform—Remington 870, 1100, and 11-87 models, as well as Benelli M1, M2, M4, and M1014 shotguns. If you want even more modularity, an optional 2-inch MIL-STD 1913 Picatinny rail version is available, mountable at the 3 or 9 o'clock position for additional accessories. It's the kind of compact, purposeful upgrade that serious shotgun shooters reach for.
