This bcg is a great find at the price. Remember this is EXO nickel boron with with a black coating applied over that wears off on contact points. I think it looks cool as it brakes in, but some might get bent that it loses its prettiness. The gas key has been properly staked and runs well with all the ammo I threw at it. Dont consider buying if you worry about form over function. I will buy again

Ive only put about 300 rounds through my rifle with the new FZ bcg. So far I'm very happy. On the cheaper end for nickle boron group and the coating is slick as snot. Fit seems right on; I've swapped bolts with other carrier(and vise versa). Definitely Happy with the purchase. If it performs as it has so far over few k more rounds I'd give it 5 stars.

I’ve only shot a few hundred rounds so far but this bcg works great. The nickel boron coating is very easy to clean and requires minimal lubricant. It also disassembles very easily for quick and easy cleaning. Highly recommended

A completely assembled, ready to install Full-Auto BCG with a Classic Finish. All critical parts are coated with EXO Nickel Boron technology that provides permanent dry lubricity, extreme durability and increases both wear and corrosion resistance. Overall a great choice for your rifle BCG.

So far, this has been a great BCG. The finish is not as supper bright and shiny as say Nib from POF, which is risiculously slick and in my experience does not discolor. I've had no failures of any kind. I've been using this in rifle with a mid length gas system. I've put at least a thousand rounds on the BCG. It's easier to clean than a parkerized BCG for sure, but it doesnt seem any easier than some of the nitride BCGs ive been using. The price i got it for was no different than nitride, but far cheaper than other nickel boron BCGs. What others have said about it changing cors is true. Mine is certainly darker than when i first got it. If its cheap id buy it again. Im curious about the Aero Nickel Borin BCG though. If i buy another, it'll probably ve rhat ine.
