Worth the money
By far this is the best BCG I have ever used and owned. I have used this in 2 different rifles, each firing at least 5k rounds. This is BCG is very robust and reliable. Unknown on 8th Jun 2020

Weird fit
i love how lightweight it is. Went with a captured spring behind it. The only thing is i think its a hair too long. Having issues getting the upper to seat with the lower. david anthony on 26th May 2020

Efficient, slick, and beautiful
Not sure how to say this is simply the best BCG I've ever had the privilege of using, other than saying it on here for the world to see. Don't bother with gimmicks, get the real deal and cry only once. Just Link Jones on 30th May 2019

Best BCGs, especially for hard use!
I've just purchased my 3rd titanium BCG from Cryptic Coatings. I have two .223/5.56 BCGs and now a new 6.8 SPC II BCG. I have run thousands of rounds through my .223 as it's my match gun and thus I put a ton of rounds through it year after year. It is now 3 years old and still looks brand new. A little bit of wear on the cam pin but that's to be expected. No abnormal wear on the billet receiver (7075-T6 Aircraft Grade Aluminum). All my Cryptic BCGs are Mystic Black. I use Ballistol to lube and the system runs like a dream without fail. I'll never buy anything other than Cryptic BCGs! Unknown on 11th Apr 2019

One bad @&& bolt
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
