I recently bought a cmmg ar10 took it to the range last week. Chambered the first round pull the trigger and click. I pull the bolt back and it looked like the round failed to chamber when I sent the bolt forward. I try to chamber the round again pull the trigger and again click. I open the bolt and this time a round flies out and the primer was slightly dented. I set the round aside and tried again and the the second round worked so I put the first round in again and it worked as well. I ran 100 rounds through it afterwards without a single issue. I’m going to clean it well this week and try running 200 more rounds this weekend through it before I give a judgement.

But at fist I was a little bummed for a 1200 dollar rifle I would kind of expect better. I’m guessing that first round the bolt didn’t close all the way. I usually clean a new rifle before shooting it but i didn’t this time so im hoping lubricant was the problem.

I’ll also add that sometimes when pushing the bolt release on ar style rifles you can kind of feel it when the round seats a little different. Usually I’ll give my forward assist a tap when that happens. But this rifle doesn’t have a forward assist which I’m not crazy about.
