Mesa Tactical Barrel and Magazine Clamps provide mount points for Picatinny rails, weapon lights and sling attachments (QD) on both sides, near the muzzle of a tactical shotgun. It is CNC machined 6061-T6 aluminum, Type III anodized to military specifications. Threaded attachment points feature HeliCoil steel thread inserts for long thread life, even after repeated mounting and removal of accessories.
Loosely mount the barrel and magazine clamp with the two allen screws before sliding on. Makes the job much easier and eliminates cross-threading.
Fits Remington 870, 1100, 11-87 and Mossberg 930 Shotguns with equal barrel and magazine extensions.
