T-Mac's Review of FailZero AR10 .308 Bolt Carrier Group (BCG)

I have been building Ar's for sometime, mainly Ar-15 and was looking to start my Ar-10 I have always wanted. Well I needed a perfect BCG (bolt carrier group) and I found it. This bad boy here will take all you can give it with out hesitation. The more you give the better it gets. The name is dead on "FailZero" no others words really to describe it. Perfect lines, expert machining and easy to take apart and clean. As we all know that's the fun part, but this makes it easy to know all residue is removed and ready to punish anything you throw at it. if you want the best, this is it.
Pros:
  • Easy access to battery
  • clean actions
  • Machine Quality
  • easy to install, exactly as advertised,
Cons:
  • None for me
Would Recommend: Yes
