Buy it
Couldn't believe the price on this. Looks great, measured in spec. Not a single nick or scratch (yet). Goes great with FDE color scheme. All in all, great value. Compare the price of this bolt to other TiN BCGs and you will be hard pressed to find a better deal elsewhere (I tried).
USQuality at a good price
I have a number of AR uppers, with a number of BCGs. One of them has a TIN BCG, which has every part coated in TIN, which I actually like a lot, so, naturally, when I decided to build another upper, I looked at another TIN BCG. TiN BCGs are usually quite pricey but this one was within a very acceptable price range. The specs looked right, so I went ahead and ordered it - and I'm glad I did. Initial inspection for fitment, and manufacturing quality, were good! No burrs, no hang-ups, and everything cycled fine. I don't have any guaging tools, but I tried the BCG with a couple different uppers and measured the headspace of fired brass and it measured good - and the ejection pattern was spot on. Couldn't be happier.

Actually, pretty good product quality made, strong and durable will buy more
USVery cool
It’s gold, so prepared to be laughed at
USThe best darned bolt carrier group on the market!
My order arrived a little early and exactly as described! The machining and finish work for this item is impeccable. The titanium nitride finish gives it a super slick gold appearance. I've ran well over two thousand rounds with it and haven't had a single malfunction!
