    Using a knife blade (a dull one) or a very small screwdriver start one edge of the rearmost ring off of the bolt and slide it around until it's off. Then the next and and the one after that. Install new ones exactly the opposite one, then the other ect. I replace rings when I can stand the BCG on end (bolt against the table) and the carrier will collapse under it's own weight.

    How many rounds does that normally take?

    Depends on the gun and whether or not I shoot it suppressed. My 10" gun which I fire a lot suppressed goes through gas rings every 1K rounds. My 3gun rifle rings last about 4-5K rounds or so, even with them heavily worn it still works.

    I notice a LOT of debate over the McFarland, I don't want to start another one, I just want your opinion on it. Is it going to hurt reliability to install one, or should I avoid them? I hear you pretty much never have to replace them.

    McFarland one piece ring is great if your rifle will function with it in place.
    They are designed to last for the service life of the bolt and the ones I have been using appear to do just that, put one on and forget it until the bolt fails.

    The problem is not all my bolt/carrier/rifle combinations will work reliably with the McFarland ring.
    On some guns I have had to remove it and go back to regular gas rings.

    On the plus side the gas ring is cheap enough you can buy one and try it out.

    Just don't stab yourself with anything when you are prying the rings out. Don't ask me how I know.

    No debate here...McFarland rocks!

    I have had one in my LMT MRP bolt for 4800 rounds and it is still working fine, one in my back up bolt with 2,000 rounds on it, same thing, and it does not fail under the "Standing the BCG on end" test. I had one in a Bushy upper as well for 2,000 rounds with no problems.

    It is the quintessential KISS part. I'll never use anything else unless I run into an upper that doesn't like them. I wish all after market parts wee this reliable.

    For the cost of one McFarland...you should try it. As always, keep this or your 3 rings well lubricated.

    Tack

    If you keep your guns dirty, they rarely fail the stand-on-end test.
