Cmmg 22 bolt, need a little help
Hey guys, I just received my new evolution cmmg upper and I am having some trouble removing the bolt and charging handle. It's factory new has not been mounted or fired yet and I want to remove the bolt and do my normal lubrication etc.... I'm not a newbie and own many ar15's but seriously this bolt will not come out of the back of the receiver. It cycles perfect etc.. What am I missing here.
