Outstanding job with the TiN and polishing! Delay in shipping for fulfillment, but well worth the wait for this price. Will need to post a further review after it’s fired, but it’s certainly built well, with great attention to the finish. Disassembly revealed further attention to detail. Wiped and oiled fully, reassembled for insertion into my upper, and It proved to be an extremely slick bcg that refuses to ruin its shine! For this price, this is a steal.

I’ve bought two of these off of optic planet because I was so happy with the first one. These are beautiful, so easy to clean and works perfect. If you look up these specs , they are high quality and tested. For the gold finish, it’s a very good value purchase

coming back to this review, im about 2000 rounds in with 0 hickups, buying another just for the heck of it. I ran this dry and wet and it performed flawlessly l, id like to say im a fast shooter when it comes to follow up so a mag dump sounds like a full auto, at that speed im dumping about 60-100 rounds as fast as possible so ive beat on this thing here and there for fun and its holding up

This Bolt carrier is insane not only it shines like Paul Walls grill when the dust cover opens. It also spits out rounds like butter. It came per oil but I added a little to it and at the range my AR sounded like a type rider spitting out 300 rounds. After the range I wiped with a micro fiber cloth and what you know Paul Wall was shining at me. Seriously best Bolt Carrier I have. Get one because I can’t believe it’s not butter!!

I just received it today and this coating looks great. This is a high quality bcg that's selling for a great price. I took it apart and viewed everything from piece to piece. No flaws. I will be using this on my 300blk 7.5 barrel with a silencerco omega 9k suppressor. This is by far my best set up. Can't wait to shoot.

The machine work and the polish is nice. Not that of a JP BCG, but at this price, it’s a good deal. The bore is hard chrome with a nice cross hatch. When disassembled, extractor freely spun on the pin and the spring appears to be a typical spring with an O-Ring and the insert. When the bolt is in the forward position and the carrier is placed vertically on a hard surface, the gas rings fully support the weight of the BCG without depressing. The bolt has the same distinctive/identical machine work to that of my OEM Sabre Defense bolt. I have yet to try the BCG, but from my initial overlook, it seems of OEM quality.
