Barrel Nut for Taccom Extreme Shotgun Magazine Extension. Barrel nut is knurled for a good grip when tightening with serrations on the bottom to ensure it doesn't work loose under recoil.
This is the barrel nut only for $20 and does not include TacCom Magazine Extension, end cap or spring. Extension tubes are sold separately and available here.
Our method of selling the tubes and barrel nuts separately allows you to change mag tube lengths without having to buy a whole new barrel nut assembly.
The barrel nuts are specific to the model of shotgun, while the tubes are generic for all shotguns.
The Extreme Extension's Modular design allows you to add extension tubes to the parent extension with out the use of couplers. If you want to expand your plus 6 to a plus 9, simply screw a plus 3 tube into your plus 6 tube. This allows you to disassemble the tubes into a more compact size for travel.
All Extreme Extensions allow for the end cap to be threaded directly into the barrel nut and allow for +1 cap for hunting conditions. The end cap is knurled to provide a good grip on the end cap to ensure it's tight. End cap also includes a sling swivel stud for convenience, yet is not in the way if a sling isn't in use.
Note: if you want to add capacity to a Mossberg JM gun, you need to replace the whole tube. The Taccom barrel nut screws to the main steel tube, not the aluminum extension. So if you want to add capacity to a JM gun, you need a tube longer than a plus 5, unless you have already changed out the stock extension tube with a Taccom tube. If you have a standard 930 and not a JM model gun, this does not apply.
