    an almost perfect transaction

    the BCG i received differs from the one pictured, lacking the MPI etching on the bolt. otherwise, this item looks really nice, and is nearly smooth as glass. i found no dings or defects, and it installed and manually cycled very smoothly. i'll be test firing it friday, and will update this review afterward.

    NiB BCG purchase

    I have purchased the NiB BCG's from other manufacturers in the past. And they were very nice; as the NiB is so much better with lubricity and any carbon deposits simply wipe off easily compared to the other types like phosphate coating where you almost need a dremel to remove the carbon deposits. When I received this BCG which was polished before the NiB coating, as I unpacked it, I almost thought it was Chromed. So shiny and nice. It was so slippery that it jumped out of my hand and hit the floor, ricocheting at such a trajectory, it smashed through my living room window leaving a warm orange haze; which indicates it was lovingly assembled. Just Kidding, about the story, but the BCG is gorgeous and probably the highest quality unit I have purchased to date. You cannot go wrong with this item as far as quality. Very nice BCG.

    Just get one!

    So I ordered one of these based on reviews and they are all spot on. Fit and Finish are fantastic and shipping was ridiculously fast. The finish is so slick, the carrier is hard to hold onto. Perfect for a special budget build or nice enough for a dream build. Don’t let the price fool you. RTB Thank you!

    RTB NICKEL BORON BOLT CARRIER GROUP

    This is the second RTB, NB M16 BCG (.223) & it works amazing in a 1982 Colt SP1 Slab Side with a Rare Breed trigger. It runs flawlessly and easy to clean. Bought the second for a PSA PISTOL build in (5.56). I'm sure it will be every bit as good in my build. Highly recommend it's a true Full-Auto BCG & love the Nickel Boron.

    Awesome BCG

    This BCG is solid. I used it for a .300 blackout build and it works amazing. I'm definitely buying another for my 3rd build.

    Great product

    With parts being hard to come by, I took a chance on this BCG with little info on it outside of the reviews here. Upon receiving it, it seemed to be of great quality and felt solid. BCG was used in a 300 BLK build and with one trip to the range, it worked flawlessly. No failures to eject, and extremely accurate being mated to a Faxon 9 inch barrel. Great product and would highly recommend.

    As expected

    The bolt seems to be quality, and works fine.
