So as you all know I recently bought a CMMG bargain bin rifle, and 500rnds of Silverbear from the Columbia, MO gunshow. Well I finally got to take it to the range today and test it out/sight it in. First two mags run fine, and I'm about halfway into my 3rd mag and I hear a click when I pulled the trigger. I wasn't out, so I go to rack the charging handle. It didn't move. I hit the foward assist. It doesn't move. So at this point I'm perplexed as those two things should at least make the bolt move a little bit. So I try to pull on the charging handle as hard as I could, nothing. I tried to pull the lower off, and lo and behold it doesn't come off because the bolt isn't fully forward in battery. the bolt lugs are meshed with the barrel lugs, but not forward and twisted to lock into battery. Oh, and thanks to Mr. Stoner's fantabuouls design, the lower doesn't come off since it won't go into battery. I've done everything I can think of, including taking the rear stock off. Nothing. I don't know if it's due to ammo, or if it's a gun malfunction. I can't see how it would be ammo, unless it's an out of spec round and jammed in the chamber and the extractor is stuck around the head of the round. If I can't figure it out, i'll have to take it to a gunshop, which I don't want to knowing it's got less than 100 rnds through it, and it's a new gun. Anyone have any idea how to fix this?
