Brownells USA 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.

Definitely recommended

Brownells USA 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.]
