Carlsons 04518 Magazine Extension 12 Gauge Benelli M1/M2/SBE I/II/III 10-Shot Blued Steel

The Carlsons 04518 Magazine Extension is a 12 Gauge tube kit designed to extend the magazine capacity of compatible Benelli semi-automatic shotguns out to 10 shots. The threaded extension is constructed of blued solid steel and installs in place of the factory magazine cap, threading onto the existing magazine tube.

This kit comes complete with the threaded extension tube, a replacement spring, and a base clamp with swivel stud set up to accept a quick-detach sling swivel. The blued finish matches factory Benelli surfaces and helps resist corrosion in the field.

The 04518 is a direct fit for the Benelli M1, M2, Super Black Eagle, Super Black Eagle II, and Super Black Eagle III in 12 gauge. It is a simple, no-gunsmithing swap for shotgunners looking to add extra firepower to their Benelli.
