After a class last year I noticed the gas key was loose on my CMT carrier. I removed the screws, cleaned them and reinstalled with red loctite. The screws were torqued to min. spec as per the USMC manual. I staked them using a MOACK.
At the range on Thursday I fired one (1) round. This is the first time the rifle was fired since the repair.

Both screws sheared. It took about 15 minutes for me to get the rifle apart. No damage except to the carrier. Sad to say the first CMT carrier I had wouldn't even fit in my receiver.
Problem permanently solved when Grant hooked me up with a BCM BCG.
