Awesome springs. Want to make it better yet? Use a bigger trigger pin . Go to .1275 instead of the loose .125 they use. A number 30 drill will work great! Grind to length on Dremel. Takes the slop out on takeup for awesome break! And use a plastic cleaning loop jag to push in spring! The pin has room to start easy then , piece of cake . Now I have an awesome Mossy setup! Thanks

My trigger spring kit for the Mossberg 500 arrived a little over an hour ago. This is the second kit I've done with your product. The first was the Marlin 795.



Once again you guys didn't disappoint me. It took me less than an hour to install on my Mossberg 500. I had checked the trigger poundage before and after the install. Stock was 6 lb 13 oz. After the install 4 lb 11 oz. Now if you can get one for my Ruger Mini 14 !





Thanks,
