Resurrecting this thread to ask a question in regards to the check. I am at about 2,300 rounds at the moment, and I just did a thorough cleaning. I lubed my bolt up so it was wet to the touch, and re-assembled the BCG after everything was clean. I did the gas ring check, and the bolt slowly collapsed into the carrier.
Do I want to do this check on a wet lubed bolt? Or should I repeat the test after I wipe the bolt down a bit???
I figured it may be time for new rings, and I wanted to do a search before I posted this this question to the boards. This seems like a relevant topic to pull up for my question.
The bolt will always fall if it's well lubed. I've also seen plenty of guns that run for a lot of rounds that 'failed' the gas ring test...so YMMV.
I was just reading the Army manual on the the M16/M4 rifle, and it notes to test the gas rings by putting the bolt in the carrier and seeing the bolt will fall out on it's own, via gravity. That seems like a much "looser" test, since there's no weight from the carrier pressing down against the rings. That also seems to dovetail with what others have noted, that "loose" gas rings will still shoot fine for quite awhile.
YMMV...
Pretty cheap insurance to be worried about if it's a good enough test if you ask me. Regardless of the parameters, have some on hand, they're cheap enough to throw a few sets in a range bag without breaking the bank.
