Joe Shmo Machinist's Review of LANTAC Enhanced Full Auto Style .308/7.62 Bolt Carrier Group (BCG)

I have had this EBCG in my Aero M5 for 6yrs. Hundreds of rounds through it. (Let’s face it, it doesn’t see the trigger time that my other 5.56 guns get, lol). It’s been flawless for me. Recently acquired a 30cal suppressor (Griffin Optimus 7) and started shooting suppressed with it. Maybe a 100-ish rnds in that configuration so far with no problems. No hiccups or malfunctions. Just flawless operation. I run a captured buffer system with it. While I could find a slightly cheaper BCG, I have had excellent performance from all my Lantac products and I trust brand. I know AR10’s /LR-308’s can be finicky, but mine has been thumping along like a well oiled machine. The BCG is the heart of any AR pattern rifle and this heart runs strong.
Pros:
  • durable coating
  • Provides smooth cycling
  • Works well with a suppressor
Cons:
  • Heavy
  • More expensive (but worth it)
Would Recommend: Yes
