Bolt handle flew out of jmpro during 3gun stage. Luckily found it after match was over. I have seen a post about installing smaller spring inside the retaining detent spring to stiffen and help prevent this from happening again. Can or does anyone have the Brownells or midway part number for this smaller spring? This is first and hopefully only Issue I have had so far! Gun runs great! Added OR3gun upgrades,opened and polished loading port, acquired extra and welded lifter and ramped forearm.
