I have a remington 870 express that I put a tacstar 2 round magazine extension on a long time ago. Well now I want to put a better spring and follower in it. I was thinking about getting this from Wilson http://www.wilsoncombat.com/store.cgi?&shop=city&cart=23073947x1278&session=3ef7c7fb04fef0c2&L=eng&P=SGSFK-EX
But I was wondering if there is something better.
There is none better than the Wilson/Scattergun Technologies spring and follower.
The spring is stainless steel.
The hi-vis follower is easy to see, plus it has a stud in the middle that allows you to feel and see if your mag is empty. Even in the dark.
