    bolt carrier staking (comparison)

    These are the AR carriers I had in our shop at the time. I will add more manufacturers as they 'come through my hands' so to speak. Of the brands listed (so far)I would only consider Colt, LMT & BCM 'proper' staking. Everything else should be restaked with a MOACKS tool by Ned Christiansen. Or at least by using a hammer and punch/chisel moving some metal into the carrier key screws. When the keys shoot loose the AR becomes a single shot or worse as it can try to feed a live round with an empty still in the upper.

    Colt







    LMT/current S&W have LMT carriers (non-Performance Center models)








    BCM carrier








    STAG/CMT/early S&W/early Noveske








    Bushmaster








    Rock River Arms








    DPMS









    after the use of the excellent MOACKS on Bushmaster carrier







    early AR10 carrier where I've used a chisel and spring loaded punch to better stake

    I guess BM and RRA have better things to do. Thanks for the pix. They really show the the quality of a company.

    I've had to fix so many of the STAG / CMMG with the top chisel/screwdriver type staking that I just consider them to be witness marks for nothing other than indicating when they've moved. Staking isn't rocket science I just don't understand why other companies can't get it right.

    Not pictured above but have excellent staking are FN contracted, FN and Alexander Arms.

    Good post gotm4 - thanks.

    I have one BM carrier and want to correct the staking. Can you described the tools and process for staking (so a mechanical idiot can understand)?

    Thanks!!

    To me with the RRA staking it is if they put faux staking on it before they even put the gas key on it.

    Thanks - I wonder if there's a less expensive way to stake
