Now I'm mildly confused. The gas rings don't serve their normal purpose since this is a piston rifle, right?

You have a ZM, very nice.
They don't but evidently you still need the tension from the gas rings to keep the bolt from camming over too soon.Quote:

If you would like to give one a try you are welcome to borrow it. I'll go someday this week to BLGC so you can join me or test it wherever you can
Thanks for the offer. But I just ordered one and should get it some time next week.Quote:

Another good add to prevent carrier drag would be a bolt spring sold by adams arms or buy one at ace hardware (compression spring #6) cut it shorter, remove the gas rings and install the spring.
While I haven't tried it, I believe my Sig716 user manual states the gas rings aren't necessary.
Sounds like some piston guns need them for proper timing, some don't.
