cmmg wasp .22 lr upper
So I have a cmmg .22 lr upper that wouldn't feed for crap so I buzzed the chamber a bunch of times and oiled the crap out of it as I have seen suggested and got no results. So on another thread someone had suggested to make sure I had a rounded hammer and not a notched one well guess what I have a notched one on that lower go figure so I threw it on another lower that has a rounded hammer and it seemed to feed better but wasn't resetting the hammer every time so what's causing that? And y would the notched hammer cause feed problems?
