So, if those shots sounded simultaneous, he wasn't following through on his trigger squeeze. :uhh: Sorry.. I'm a pain about fundamentals like that.
I've worn out a couple m-14's at Team 1 and haven't seen that issue. Interesting. Sure was quick.
What is the Mag capacity on the M-14? 10 rd box?
Are they still using them as a DM?
Broken disconnector return spring. I had that happen on a 416 I was dialing in... Pull the trigger BOOM, release the trigger BOOM. It's an easy fix.
And yes, REAL M14s were full-auto, though there was a semi-auto lockout key.
