    1. Great product

      I had a problem with vertical stringing in 308 build and switched out carrier with cryptic carrier. Completely fixed problem, great finish even on basic manganese phosphate, and very well built. Shipped fast and great customer care. I will use cryptic from now on. on 5th May 2016

    2. Nice Attention To My New Build

      Just received my nickel boron carrier. First class product. Very slick coating and well made. Will be buying more for future build projects. Would definitely recommend. on 20th Apr 2016

    3. Haven't shot it yet

      Just received my carrier. It comes well packaged. The carrier is flawless. It looks and feels great. Would definitely recommend it. Very nice kit wouls recommend it. Fast shipping and handling. on 18th Mar 2016

    4. Quality Mil Spec Straight From The Source

      Glad I found these guys, little bit of research pays off. Will be using these for all of my future builds. I just got the basic magpho coating, but the finish is even on the whole bolt carrier with no tool marks of any sort. Money well spent. on 1st Mar 2016

    5. great product

      So much to say about Cryptic Coating BC. I got the mystic silver and was very pleased with this product, it simply would not stay in my hand cause how slick and smooth it is. I think of this product as jewelry for an AR. The build quality is well done and it's worth spending the money for a Cryptic BCG. I just hope that Cryptic Coating can have the light weight Titanium BC in there coating. on 30th Mar 2015

    6. Pretty Slick!

      Just finishing up my .308 build with your Mystic Black bolt carrier. I went with high-end barrel kit from JP, Timney trigger, Vortex Viper LR optics... so I figured that I should invest in a bcg that would be easy to clean (and look at!). Looking forward to getting to the range with it. on 30th Dec 2014
