Most Helpful Positive Review Cryptic 223/5.56 BCG
I bought the Cryptic 223/5.56 mystic silver chrome BCG. This BCG is amazing. The quality of this BCG is very nice. The cleanup is a breeze. It ran flawlessly. I would definitely recommend this BCG for anyone looking to upgrade or use in a new build.
Most Helpful Negative Review Decent BCG
Bolt came packaged jn cheap clear plastic clam shell similar to packaging for a cheap knife you’d find on the end isle at an outdoor outfitters. Bolt is very stiff inside carrier. Is difficult to remove for dissemble and bolt literally has to be slammed back into carrier to reassemble. Staking on ga...

Cryptic BCG

by SA594, Verified Owner from HI, United States Written on July 31, 2025
Took this BCG out for a range session and so far so good, ran smoothly with no issues and clean up was a breeze. Will definitely be running this harder and more frequently, based on what I've read and seen the results should be the same..

I now own 3 of these BCG

by Mr Orange, Verified Owner from CO, United States Written on June 27, 2025
I am also the proud owner of a Geissele BCG, Micro Best BCG and Tool Craft Nickel boron BCG. I love the cryptic coatings lubricity. I always find the Cryptic Coatings Nickel Boron Bolts on sale and put the others up for backups. The price is negligible so I figured just get the entire BCG. I have a Mystic Black and 2 Mystic Bronze. The Black did indeed come with a loose bolt and its tolerances could have been better. But again it did work and is now a backup anyway. With the nickel boron bolt it runs as good as my Geissele. It was another Bronze one or a BCM BCG and the BCM was $20 more because of a sale. The ironic thing is I would pay $20 more for the Cryptic but not vice versa.

I am still wanting to get one other company that I have a friend who has one but they are sold out until Dec. Those would be the only ones I would want over these and I am not saying the name on purpose.
Pros:
  • durable
  • reliable
  • Smooth
  • Looks
  • Quality feel
  • Easy clean
Cons:
  • Nickel Boron Bolt works better than the pretty ones
  • Gas rings were worn on one unit when purchased
Best Used for:
  • cold weather
  • builds
