Available for these brands: Benelli, Beretta, Browning, Mossberg, Remington, Winchester, FN, CZ, Stoeger*, and Franchi.

Nordic's new MXT Shotgun Magazine Extensions feature a clamp groove to allow their clamp to fit more precisely on the tube and all shotgun barrels. The tube is now reversible so you can position the clamp where it best fits your shotgun or between the barrel rib lands. These feature a new end cap designed exclusively for the new MXT extension tube.

Machined from strong lightweight aircraft grade 6061 aluminum tubing, you can add anywhere from +1 to +9 rounds. Barrel nuts are designed to match OEM styling. Kit includes: barrel nut, magazine tube, spring, and end-cap. Nordic recommend using their Low-Drag Follower and their Shotgun Tube Clamp for the best performance. Nordic's tubes have an OD of 1.06″

NOTE: While it is OK to have your extension protrude past the muzzle, you may experience a carbon build-up, scoring or discoloring of the extension, especially when using a ported choke tube. Cosmetic damage of this sort is not a warranty issue. 

NOTE: Clamp shown only for reference, and is not included. Please order clamp separately. +1 MXT Magazine Tube Extensions do not feature the clamp groove.

*Recently, some Stoeger M2000 shotguns not accepting Nordic magazine tubes. It appears that Stoeger has changed the specifications on the M2000 mid-production, and successfully fitting the Stoeger M2000 extensions will not be possible on certain M2000’s. If you find that your Nordic Components Stoeger M2000 extension does not fit, simply return it for a refund. 

NOTE: Extensions for the Browning Auto-5 (MXT-BP) Fit OLDER Auto-5’s only. Extensions for the new Browning A5 (MXT-NA5) Fit the new inertia-operated A5’s of recent production.

    Great Mag tube ext.

    Posted by WitchDoc on 14th Sep 2022

    Great fit and finish and sturdy. Couldn't ask for any better. I felt a little strange needing to cut the spring--worried it would be too short, but turned out perfect!

    Fits as advertised

    Posted by Scott on 17th Feb 2022

    I just received and install this on my Franchi Affinity 3 and it was a perfect fit. It appears to be made well, not plastic. I bought the +6 and it is 1 1/2” shorter tha n my 28” barrel as advertised on the size chart. It does not appear I will need the support clamp because it is so well made and fits well.

    Nordic components are made of quality materials and the finish is very good as well.

    Great for 3 gun!

    Posted by Ranger on 26th Feb 2018

    They had the best price for the whole extension kit. I got the plus 5 for my Beretta 1301 comp for a total of 10+1. The fit and finish is great, reliability is 100% and not too heavy. Shipping was fast and from North Carolina so it was like buying local.

    Simple installation

    Posted by Unknown on 4th Jul 2017

    Received the product and found it super easy to install. Fit is perfect. Ordered the +5 extension found it only added 4 2&3/4 in shells. Not a problem, going to get an extra 3 3 in shell's when goose season gets here.
