CMMG MK 47 Mixed Results

[georgeib]

I'm running tests now. It seems that if you can load it you can shoot it - IOW - If the first round loads its OK. I learned at the range that the dud mags won't even load the first round and its a nose up problem. So now i will run snap cap tests on my mags. I seem to have a Chinese mag handy that might work, and the cheap Bulgies seem OK, but I am stocking on PMags and they will be dedicated to the MK 47 - they do look right in this gun, but not in an AK - just me.

Nice fit means nothing in this gun. Must test.

Another thing - much is made (by CMMG and the 'test' crowd) about how thin the bolt head is on 7.62x39 ARs, and how that can/does lead to breakage? Is there evidence for this?

I was reading a few years ago that 7.62x39 AR bolts were failing at 1000-1500 rounds. I seem to recall seeing some pics.
