    1. Perfection.

      I purchased a blem mystic gold. Still cant find a blemish anywhere. It a great focus point to my rasta themed Ar15 build on 24th Aug 2020

    2. Great.

      I ordered 2 BCG's one in a .223 and the other in 6.5. The order shipped quick and without hassle. The .223 works like a dream, but haven't got to try out the 6.5 yet. Both BCG'S were worth every cent. I will definitely be using cryptic for my next build. on 24th Aug 2020

    3. Glad the QC inspector needs glasses! Perfect item!

      I couldn’t find a blemish on this thing- but I am glad they allowed me purchase it as a blemish!!!! I love to save money on quality products. It looks absolutely perfect, this is my third BCG from cryptic coatings and I couldn’t be happier. on 17th Aug 2020

    4. Slickest BCG on the market!!!!

      If you haven't tried a Cryptics Coatings BCG then you're missing out. I've had many different BCGs from big name companies and this is by far the best one I've ever owned. ALSO THE CUSTOMER SERVICE IS TOP NOTCH. CALLED AND SPOKE WITH SUMMER ON SEVERAL OCCASIONS AND SHE WAS EXTREMELY PROFESSIONAL AND SHE WENT ABOVE AND BEYOND TO HELP ME OUT AND ENSURE I GOT WHAT I NEEDED. I can't say enough great things about this company and their products. They are now my only choice for a BCG on any platform I build. on 14th Aug 2020

    5. Blemished?

      First if I’d like to say extremely fast shipping. Ordered a blemished.308 BCG at 12:30 am was sent out same day by 6:00am. As for the blemish what blemish lol this thing looks Immaculate. I will most definitely be ordering from Cryptic Coatings again on 12th Aug 2020

    6. AWESOME is the word

      love the product and it was lightning fast shipping , I purchased the blemish product and I still cant find one.. on 11th Aug 2020

    7. Awesome

      Works great on 10th Aug 2020

    8. Do it.

      Ran into a lot of haters out there, saying not worth the money. I completely disagree with them. Glad I didn’t listen, I pulled the trigger and bought it. IT IS AMAZING!!! I’ve already run over 1,000 rounds through it. It’s as beautiful as the day I got it. Cleans up with a towel, no cleaner necessary. on 9th Aug 2020

    9. BLEM Coated BCG

      The BCG arrived very quickly. After breaking down the BCG I did not notice any blemishes or other issues indicating a less than perfect part. Great the finish on this BCG is beautiful! on 3rd Aug 2020

    10. Save the extra cash for extra parts

      Ordered the blem, since the bcg sees action and you only see a small part of it. Who cares if it's blemished. Had superficial marks that wiped off with the included cloth, way better than expected and saved a few dollars for some other part.

      Thanks guys! Love this BCG       on 3rd Aug 2020
