Hey guys, do any of you know where to get an after market firing pin for the mvp in 223? Mine seems to be to soft, because when shooting it, if at all in repetition(like 15-20 rounds in about 5 to 10 minutes), the end will swell, and not allow the pin to pass through the bolt face. I am using reloads, but not particularly hot loadings. Has anyone else had this exact problem? I have seen some other posts that are similar, but not the same. When this problem happens, I am forced to disassemble the bolt, and re-size it with emry cloth or sand paper, which is not exactly apealy get to me both for time's sake, and the gun's. Any feedback would be greatly appreciated! Thanks!
