    BACK FROM THE DEAD

    I just ordered a Young Mfg. FA BCG- has any one else been using them? I couldn't justify buying another BCG for $130 and sending it to Robar for another $130 for the coating. The Chrome Young BCG cost about $160, and extra $30 wont break the bank.
    Let me know what you guys think.

    The web site for Young Manufacturing is http://www.newriverarms.net/store.php?pg1-cid38.html

    Their National Match carrier is suppose to be 1/2 heavier than a standard carrier, but I don't know if they mean M16 carrier. It also has more contact area with the upper receiver. Service rifle shooters like heavy carriers for softer recoil and smooth operation which is why Young is marketing it. David Tubb also makes a system (CWS) so you can add/change weights of the and tune your carrier to where you like how it feels. 3gunners like lighter carriers because when combined with a muzzle brake and/or an adjustable gas system a rifle can be made to shoot very soft and fast with little or no muzzle rise.
    I looked at a lot of different carriers for my 3gun rifle and finally decided on the very light JP LMOS carrier.


    Here's some weights of carriers that I've personally measured.

    bolt carrier weights (w/o bolts but with carrier keys and screws)

    JP stainless LMOS (lightweight) carrier 6.25oz
    Young Mfg (lightweight) 8.60oz
    Colt non-shrouded 1/2 circle carrier 8.63oz
    Colt shrouded 1/2 circle carrier 8.87oz
    Bushmaster non-shrouded AR15 carrier 8.92oz
    Bushmaster shrouded AR15 carrier 9.26oz
    CMT M16 carrier 9.46oz

    Good info- I asked because I ordered one last night. I ordered the Young full auto carrier and an LMT upper and I'm sending both to PWS for their piston system to be installed.
    It looks like they(Young) have 5 different carriers now and that's what sparked my interest.
    Check them out:

    Could you please clarify that? How a chromed BCG would not work well in a billet upper.

    Sure. Billet uppers tend to me be much tighter (internally) and chroming tends to be thicker in some spots then it should be. Combine the two and you get drag.

    Aye,

    thats the reason when I whent chrome using a MUR I used Ionbond to PVD chrome onto my BCM carrier.4k rds and still looks like new.the inside of the upper has the typical wear marks as any other would.
    a lot of things are using PVD in coatings, magazines, AR recievers and I THINK S&W is doing slides like this also.

    To be honest, I haven't found a need for a chromed carrier yet.

    I was going to say I think I would consider using W-DLC (ionbond) since the base layer of W-DLC is chrome, with a tungsten impregnated coating over it. Can't really get much tougher then that. BCM has them.

    The thing is though, I'm not sure which is "slicker" and less pourous, chrome or W-DLC. Can anyone compare the two for this application (internals)?

    Same here. People say it's easier to clean. But the hard part to clean on a Standard carrier is already chromed. (the inside) The outside is easily wiped down with a brush/rag.

    The idiots on TOS used to always say that a chromed carrier would wear out your upper faster. Yeah, stupid! A slicker surface is going to increase wear!

    In any case, I see no use for a chromed carrier.
