Best BCG on the market and the finish is great! I have bought them both ways and I will need someone to point out the finish flaw to me because I do not see it! Unknown on 19th Feb 2018
WOW enough said. Amazing product, I've looked this thing over and if its blemished I cant find it. I put 300 flawless rounds through it and wiped it clean with a dry paper towel. saving my $$$$ for another Unknown on 2nd Feb 2018
I could not find any blemishes it fits perfectly I will buy from them again Unknown on 24th Jan 2018
I ordered the "blemish" to save a little money. When I received the BCG, I couldn't really see anything wrong with it. The exterior polish was good, so was the interior that I could see. The logo might have been just a bit off center, but it still showed fine when the BCG was seated in the rifle. Overall, a great product. Scott on 8th Jan 2018
Every penny well spent, could not find any sign of blem. Amazing addition to the arsenal, smooth snug amazing feel! would recommend to everyone! Unknown on 5th Dec 2017
If you are using you ar15 for home defence or self protection in a SHTF or TEOTWAWKI situation,
when you life is on the line you need to know that your equipment will not fail.
I have had a cheap bolt carrier group explode on me at the range, I replaced it with a Mystic Black.
Yes, it cost more then most BCG out there, but there is a reason why "TOP QUALITY".
It's guaranteed for life! Cryptic Coating stands behind their product, you will never have to buy another bolt carrier group for your weapon and their customer service is great.
The Bolt Carrier Group is the hardest working part of an ar15, pay a little extra and buy quality!

I have yet to build the AR10 this gorgeous BCG is going in, but I have to say, WOW!!!
I bought the Mystic Black BCG for .308 and it is amazingly beautiful. Feels slippery as $#!t on oil on top of ice.
My favorite 3letter bolt has been surpassed.
If the finish holds up, there's no doubt it's an amazingly well done BCG. And if so (And I believe it will hold up), I WILL be buying more of these...

I ordered a blem bcg to save some money. Fine toothed comb and couldn't find an issue. Runs just as perfectly as the TiN bcg I have. Always recommend Cryptic Coatings. Ordered the BCG and had it in my firearm in 2 days. Nothing to complain about. Unknown on 5th Oct 2017
This BCG is wonderful, I can feel the responsiveness as I shoot. The difference is very noticeable. It also looks spectacular. Unknown on 3rd Oct 2017
