Description

This is a five piece extended magazine tube kit designed for use with 12 gauge shotguns to increase overall ammunition capacity. The kit features an extended magazine tube constructed of metal with a matte silver bead blasted finish, featuring an integrated knurled mounting nut and a black finished rear attachment plate. Accompanying the tube is one long high tension steel follower spring designed to ensure reliable shell feeding, along with a black metal barrel clamp and a single securing screw. The assembly is completed by a black polymer magazine follower and an elongated black polymer internal shell guide or spacer. No manufacturer markings, model designations, or serial numbers are visible on any of the components. The design and mounting plate configuration are consistent with aftermarket extension kits intended for semi automatic or pump action shotguns.


Condition report:

The magazine extension tube shows a clean matte silver finish with minor surface scuffs and light handling marks. The black finished mounting hardware and barrel clamp exhibit minor wear at the contact points but remain in good functional condition. The steel follower spring is under tension and appears free of rust or kinking. Both the polymer follower and internal spacer are intact without signs of significant wear or degradation. The interior of the extension tube is clean and unobstructed.
