    1. Best BCG coating ever

      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! on 24th Oct 2020

    2. Fantastic BCG

      I own 5 of Cryptic Coatings BCG's wouldn't consider anything else you of the line enough said. on 20th Oct 2020

    3. Possibly the prettiest BCG I've ever seen

      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.

    4. Beautiful

      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! on 12th Oct 2020

    5. Superior

      This product is well made and easy to clean. Works flawlessly. Good job!

    6. Above and Beyond

      Phenomenal function, visual and overall quality from shipping to buying. 100/10 Would recommend. on 9th Oct 2020

    7. Very nice

      Very nice, smooth, and flawless. It came in quicker than expected. You'll get a lot of "ooooooh, what is thats". Just as slick as nib, worth every penny. on 9th Oct 2020

    8. Expectations exceeded

      I got the Gold BCG and my hands hurt from trying to hold onto it. It is super slippery and will slip through your hands if not held tight enough 10/10 may buy another as a gift to a friend. on 8th Oct 2020

    9. Smooth, gold and amazing.

      Perfect fit, runs smooth and cleans extremely easy. on 1st Oct 2020

    10. Great BCG

      I waited for this one to come back into stock. I did a bunch of research on what BCGs are the best. This one is so smooth and it looks great too. Not disappointed with this buy. I also have my buddies looking to get these too for their new builds. on 29th Sep 2020
