Mr.M's Review of Cryptic .308 WIN/7.62x51mm Bolt Carrier Group (BCG) - Complete

To review the assemblies before installing I take the bolt & firing pin out all my BCGs to check. I noticed the gas rings gaps were not stagered (separated) but coinciding. I did't like that, that is my only issue. I separated the rings openings and it looks like it works well.
I recommend to always check the ring gap spacing before startig using any BCG
Pros:
  • solid
Cons:
  • inappropriate ring gap spacing
Would Recommend: Yes
