Yeah I do remove bolt and pin. I use fire clean on it. It's done great for a long time no issues at all even would shoot light loads good.I will call you or pm you with my address and maybe try a stock spring. Thanks fir your help and info.
I clean it before each match. I will tear it back down and see what i can see. Both me and my son shot it at the Atl 3Gun last Sunday it did maybe 3 times out 150 rnds. Thanks for your input.
I have a M3k with MOA trigger work done to it. It has about 600 rnds and has just started having a light primer strike once and while. Any Ideas?
Thanks,
PS.I use top gun shells and gun club
