Love it!! So easy to clean! Wish I could’ve gotten it in blue though ! Unknown on 25th Nov 2020
Packaged neatly and was pre lubricated out of the box and felt great to hold in the hand.
Tough as it is clean. Craftsmanship is incredible.
Ran in the AR smoothly. Very much worth the money.

Absolutely love this BCG. Easy to clean and looks great. I bought the mystic blue version but it's clearly a silver appearance. Not complaining as much as I am making a point for those of you who think blue means blue. I will buy this brand again for my next AR in the future. Kenny U on 18th Nov 2020
Always as good as the last... only BCG I use Chance Bishop on 29th Oct 2020
Bought another Cryptic BCG, pretty soon I’ll have one in every color! By far the most slick feeling coating ever and easiest to clean, it’s amazing! RonH on 24th Oct 2020
I own 5 of Cryptic Coatings BCG's wouldn't consider anything else you of the line enough said. David Furr on 20th Oct 2020
I bought one of these for a client build, and looked over the specifications for the Mystic Black coating very carefully before I selected it. When it arrived, it was beautiful. I haven't torn it down yet, but it is well designed, and has an almost sensual feel to the finish. It's absolutely beautiful.
I will probably be buying these for every high-end build I do from now on, as long as Cryptic Coatings can keep up with the demand. My only complaint about them is that the process is time consuming, and as soon as they come in stock, they're sold out.
I'll know better how they perform after I put a couple of hundred rounds through the rifle, but if the BCG works as well as it feels, it'll be a top notch performer. John W on 14th Oct 2020
I bought the Gold and this thing is an attention grabber. Everybody loves it when they see it! Very well made and overall a very high quality piece. Shipping was quick. I believe I ordered it on a Sunday and received it either Wednesday or Thursday of that week. I’ve already recommended to several others! J. Brown on 12th Oct 2020
This product is well made and easy to clean. Works flawlessly. Good job!
