    McFarland Gas Ring vs. Standard

    I have been using a McFarland gas ring for the past 500 rounds without a problem; I have heard since boot camp "never let those 3 gaps in the gas rings line up otherwise you will have problems"...5 years using standard 3 gas rings and never had a problem.
    I would like to acknowledge that many of you know a lot more about this subject than me.
    Can anyone tell me if using the McFarland has downfalls or any other negative effects?
    Thanks,
    Dave

    I don't have any experience on the McFarlane rings.

    I will say that the alignment issue is bullshit, and I have successfully fired hundreds of rounds in succession with only two rings on the bolt.....don't know where that third ring went.

    We had some professional user guns that had the McRings installed, they did not run well. We did a once over and replaced the rings with 3 piece unts and all was good. I have an SP1 Carbine that I ran the crap out of when I was young, well before I knew what gas rings were, when I finally got around to replacing them they were sharp half moons...totally worn, gun still ran well though, I call BS on the alignment issue.

    i tried them years ago, and they were very tight, and caused some problems when dirty (bolt not going into full battery), which didn't happen with regular rings. didn't loosen up much even after half a case of ammo. ditched them and went back to regular gas rings.

    As Pat Rogers pointed out in a recent SWAT article and here (https://www.m4carbine.net/showthread.php?t=31)

    The carbine will run with one gas ring

    I am not impressed that McFarland perpetuates that rumor in their advertising

    Colt Armorer Instructor Dean Caputo makes the same point in his class: all three spaces lining up lining up is a non-issue as it will run on one ring.

    We all know that a weapon will run with only gas ring. What I like about the McFarland rings is that quality of the materials and that I don't have to change them out like I do standard gas rings.

    I don't have many rounds downrange with them installed (yet), but so far so good.

    Never had much use for them... The Stock 3 rings always worked well.

    If some one gave me a few for free .. but for me to pay for them.... Homie don't think so....
