Simple tool for 870 magazine ext. install - XS Sight Systems Magazine Tube Detent Swage - Rem 12 ga RE-7000-1

An essential tool for installing magazine extensions on 870 shotguns and clones. I have an H&R pump which is a Norinco manufactured clone of the 870. I purchased a Blunderbuss Technologies +2 extension and just like the 870 the magazine tube is dimpled. This inexpensive well made tool is the best way to go of the various methods for removing the dimples. Before beginning I measured the ID of the tube and the OD of the tool. The tool was properly sized and had proper clearance. The tool worked exceptionally well for it’s purpose. The only negative of the tool is the surface finish of the swage portion. It is serviceable but for its purpose a polished finish is preferable and as such I polished the surfaces with 320G before usage. Not necessary but recommended. Additionally follow the directions and use sufficient high quality grease and a brass drift to metal work the dimples with the swage installed.
