Lefty AR Builder's Review of Cryptic .223/5.56/.300 AAC Blackout Left Hand Bolt Carrier Group (BCG) - Complete

There are not many lefty AR parts to begin with, so choices are limited. I got this one, and it’s more expensive than many options that are only available to right handed BCGs. So it was among a select few LEFT options to begin with. It looks well made. I haven’t used it yet, but the finish being smoother and brighter, to me means less friction, and easier to know when I should clean it, compared to a flat black one. I like it. I would like it more if it were less expensive.
Pros:
  • LEFTY, Nice finish
Cons:
  • high price
Best Used for:
  • AR reliability
Would Recommend: Yes
