| I have the most recent version of BHOA in my CMMG M4/22 upper, and the problem I'm having with it is it's locking my bolt back with rounds still in the magazine. And since it happens 2-3 times per magazine, I ended up having to remove it all together for now. The weird thing is that I'm using it with BDM X-Form magazines w/ SS lips, that don't even work with BHOA, so I'm not sure what's going on. The only cause I can think of is that the tab that catches the bolt is bouncing up and down from recoil, but not sure how to fix that. Any ideas? |
