Wrong spring for Mossberg 930

This is a good quality part however if you have a Mossberg 930 the supplied spring will not work. The coils are spaced too tight, causing too much tension, even if the spring is cut down. The Mossberg factory spring works well with this extension.

Must Swage the Magazine First on Tac-14

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.
