Magazine clamp includes 3.5" picatinny rail.

 Mesa Tactical Magazine and Barrel Clamps provide mount points for Picatinny rails, weapon lights and sling attachments near the muzzle of a tactical shotgun. Both designs are 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.

  The Mesa Tactical Magazine Clamp can be used to more securely retain aftermarket or factory magazine extensions, while at the same time offering flexible accessory mounting options near the shotgun muzzle.
