I just got mine in mail and already I can tell the difference in weight. I got this because I just got an echo trigger and I wanted a bolt that could hold up to it. So far it works great. Not to mention but this company has some of the best customer service. Ryan LBS on 31st Aug 2017
Very pleased with Cryptic Coating Very well made product durable and looks Killer in my $keletonized Ar 10 & AR 15 builds. Hats off to another great American made company!! Unknown on 11th Jan 2017
So my neighbor got a mystic gold bcg from these guys right after I got a fail zero and did a pof roller cam pin upgrade. Even with mine oiled, his was smoother. Then after going shooting and his just wiping off and mine had discolored from heat and carbon(we run suppressed) I was sold. But I wanted a lighter mass carrier with my ultra lightweight build and because I have a jp industries silent capture kit with the adjustable spring kit I just so happened to drop the green spring into my buffer. Boom, cycled smoothly and didn't short stroke any rounds, perfect. I got lucky, I didn't have to play with it at all. Tried 4 types of ammo, from crappy Tulammo to lake city 855's. Flawless. The bcg is so slick that it was noticeably quieter than my old one. Could not be happier.
Thanks again cryptic coatings!!! You're the best!!!! Unknown on 18th Dec 2016
Major props to Ms. Karen for keeping me aware of when this hard to obtain item was available this BCG has been a smooth running piece of machinery. Dante on 22nd Nov 2016
This is the lightest and best made BCG that I could dream of. You made this dream a reality. Thank you so much for true dedication to your work. A brilliantly made BCG and a real marvel to shoot and clean. Matthew Wellington on 16th Aug 2016
Perfect balance of light and strong. This BCG reduced weight, and thanks to the slick coating, dramatically shortens cleaning times. This is my 2nd Cryptic BCG and won't be my last. Unknown on 27th Jul 2016
I go to the DFW Gun Shows Looking to get my hands on different Cryptic Coatings... These are hard to find but this is the best BCG you can grab. It's slick shiny I stay away from the standard BCG because the coat is slick and easy to clean it helps cycle the ar fasterer than a Lantac, standard BCM, standard spikes tactical BCG. I'm on my 2nd BCG from cryptic coating. I have the silver and ordered the mystic black... when I have the money invested in to my build I refuse to settle for a standard BCG... Cryptic Coating is the best period and worth the money if you want a a quality upper make sure you put this in your ar15 build Chesty The Bulldog on 2nd May 2016
