Very nice BCG

by Krock, Verified Owner from OH, United States Written on February 4, 2026
I’ve been extremely impressed with the Cryptic Bolt Carrier Group. The fit and finish are outstanding, and the coating is absolutely top-tier—it cleans up effortlessly and still looks new after plenty of use. Reliability has been flawless so far, with smooth cycling and consistent performance. You can tell this is a high-quality, well-machined component that was built with attention to detail. It’s a premium upgrade that actually delivers on its promises, and I wouldn’t hesitate to run it in a serious build or recommend it to anyone looking for a dependable, high-performance BCG.
Pros:
  • Smooth Cycling
Cons:
  • Price $$$
Best Used for:
  • AR15

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..
