Stripped carrier is finished in an Ion Bonded Flat Dark Earth. Lowers friction and cleans easier, however the carrier still needs a thin coat of oil on it at all times.

    Fde bcg

    I had to buy this from brownells because they were out of stock here but their bcg is very nice, smooth and there’s something to be said about a company that puts their logo on their product. Not to mention the fde looks awesome. Why wouldn’t you pay the extra $10 for it!!?? It also shipped with a little rubber o-ring for the extractor which was easily installed.

    Slides very nice in receiver. Bolt very smooth in its
    movement. Gave 4 stars only because have not shot
    it yet. But I'm expecting it to be just fine.

    BCM BCG (in FDE)

    Posted by Hank Tam on May 1st 2020

    Bought BCM BCG for previous builds and all have functioned flawlessly. Why not buy another for my 300 BLK build—in FDE? Yes. Please. Saucy AF. Ships fast. Nuff said.

    I put this bcg in a bcm upper and it’s all just so smooth. The fde cerakote looks and feels great. I would like to put this group in all my rigs.

    You could use some color in your life

    Posted by Kyle Hamilton on Apr 25th 2020

    All the excellent quality, function, and operation of your usual BCM bolt, but in a snazzy carrier. Compliments burnt bronze cerakotes and FDE builds nicely and contrasts well when applied to your "scary" blacked out guns. If bland, basic, black BCGs entice you then fine, but this one is for those who drink with their pinkies up.

    Runs great, no issues. Haven’t had it long but over 1000 rounds through in about a week or so, so again, no issues. Will buy again
