This Bcg is amazing. I used to have a BCA Bcg for my ar-10, but once I changed my Bcg to cryptic it’s a game changer.

I don’t know what magic or pixie dust cryptic used on this product, but I’ll highly recommend this Bcg if y’all are looking for a new Bcg for your current build upgrade or future build project.
Pros:
  • Easy to clean
  • reliable
  • Colorful
Cons:
  • a little bit on the pricey side
Best Used for:
  • hunting
  • Range

optics planet shipped it quick. UPS dropped the ball. UPS either delivered it to the wrong house or took it with them. But optics planet took care of me. i ended up going with another lantac. but i plan on getting another one off these in a few weeks.
