If the BCG collapses onto the bolt then the rings are worn and you need to replace them.
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.
