DIGIMAN's Review of Cryptic .223 / 5.56 / .300 AAC Blackout Low Mass Steel Bolt Carrier Group (BCG)

Runs great for subsonic 300 blk. Seems to be gas efficient. Perfect for a low recoil build coupled with an adjustable gas block, reduced power spring and a 1.7 ounce buffer I had zero malfunctions. Works with an FRT but needs a h1 to reduce bolt bounce and light primer strikes.
Best Used for:
  • Subsonic 300BLK
Would Recommend: Yes
