Stoeger M3K(22/01/2017)
I bought a Plus 6 Nordic Components tube for my Stoeger M3K. total rounds 10 plus one in the chamber. It was easy to install, it has a great finish. Just make sure you buy the right Tube Nut for you shotgun.
Fantastic quality at reasonable price(21/07/2017)
If you're asking yourself, "Will it really be that much better than some of the cheaper alternatives?" the answer is, "Yes!" I put this +6 under a 28" Stoeger M3k and it fits perfectly (just shy of reaching muzzle). I have cheaper tubes on other guns that "get the job done" but have learned Nordic really is a cut above. Fit and finish perfect, spring is superior quality. Everything installed in minutes, runs like a champ without further adjustment. Super happy. [Buy the clamp too! Fits in tube's groove nicely to prevent sliding, very professional-- totally different league than other less expensive alternatives.]
absolute necessity(17/01/2017)
This magazine tube extension kit turned my benelli m2 field into an excellent clay shooter, 3-gunner, and all around better gun. The installation is as easy as screwing it on and cutting the spring to length.
My benelli M2 came with a 26" barrel, and this tube ends up being about a half inch longer than the barrel.
Be aware that this kit comes with the extension tube, end cap, and spring ONLY!!! You still need to purchase the extension tube nut to mount this kit to your gun!
Look up the Nordic Components extension tube nut 12ga.!

Must Swage the Magazine First on Tac-14(04/04/2018)
Mag extension and Remington Nut from Nordic Components work well AFTER you swage or grind the dimples out of the end of the magazine tube. I used the 006-000-119WB Magazine Tube Detent Swage-Remington 12 Gauge from Brownells. I re-used the standard Remington Spring and so far so good. No feeding problems yet.
Should accommodate 6 standard 1/16" crimp 2 3/4" shells tightly in the magazine of a Tac-14 after dimple removal. I use the S&B 00 Buck which has a 7/32" crimp so I only get 5, but boy do they rip.
