Thread: McFarland Gas Ring vs. Standard

    With regard to what buffers are come in Colt Commandos, I have seen standard, H, and H2 in USG 11.5" Colts. Who knows in what configuration they came from the factory...??

    The US military now supplies(new stocks) all H2 buffers for the m4 series. I have seen this in US Army & USN repair shops.

    Of note, sometimes a H2 buffer will impead function in extreme cold at extreme altitude. Perhaps a function of the above & new weapon with tight gas port. Probably only a handful of people in some units have experienced this.

    I have some friends that have some Commandos and they came with H buffers (which is why I was surprised to hear that they come with carbine buffers). I sometimes wonder if Colt just doesn't stick whatever they have in stock in them at the time.

    I knew I could find it:

    http://www.dtic.mil/ndia/2003smallarms/john.ppt

    CQBR PPT from Crane. It DOES show what looks to be a 1 piece gas ring.

    Two points I guess I'd make thou:

    1. who knows if the rings were ever implemented
    2. people are allways LOOKING for a better mousetrap, however
    that doesn't mean they allways FIND one.

    From what I've heard about Dean Caputo I would trust his advice to save my ass in a fight, so there ya be.

    Dano, good to see you here man!

    Good find on the PPT! Hadn't seen that one in a long time.

    That is a McFarland gas ring. I also called them and asked if the Military purchased them and they said yes (tons). So they went somewhere for sure.

    I personally don't think that there is an issue with standard gas rings. My point is if the McFarland gas rings are the same price as standard gas rings and are made out of better materials why not use them? You just might get a more reliable weapon because of not having to PM that part as much.

    I have now shipped 20 of my FN contracted BCG's out. All of them have the McFarland gas rings. We shall see how they run for folks.

    FWIW- i have seen a bunch of the Reliability Enhancement Kits and all have had 3 piece gas rings and "O" rings. None have had defenders ot the one piece gas ring, which leads me to believe that what you see in any particular kit is the result of when you saw it.

    Makes sense Pat, as a lot of this stuff is COTS so the Govt uses what the Govt can find.

    Macfarland v. standard

    My experience with the Macfarland vice standard gas rings has been poor. The Macfarlands seem to seal much better than the GI rings, which brings problems after you've blown out or dirtied-up the lube in the carrier -- drag increases in as few as 20 rounds. Add a suppressor and you can pretty much guarantee you've hosed yourself.

    In competition M16s and SPRs they caused enough alibi stoppages that it wasn't worth it, and you almost had to put a couple of drops of lube in the carrier lube hole for each ten-shot string in the national match course.

    Strangely, though, they seem to work great in the AR-10.
