MICROBEST AR15 5.56 C158 MPI ALL-CHROME BOLT CARRIER GROUP, PREMIUM
Haven’t had a chance to go to the range to test it out, but fit and finish are great and if it is like my other Microbest BCG there shouldn’t be any issues

Microbest BCGs
As usual Arftac comes through w/ good stuff at a fair price and quick deliveries. Will be ordering more soon.

Gucci BCG at Trailer Park Price
I've got two of these I'm running in SBR builds that are also dedicated suppressed. They're incredibly gas efficient. Add in OCKS and Sprinco and you'd be stupid to spend more on a BCG. I know because I did.

Microbest Chrome BCG
The order was processed and shipped quickly and the packaging was great. While I haven't checked the dimensions of this BCG yet, the quality looks to be excellent. If anything happens to be off (seems unlikely), I'll update this review. It's nice to see ARFTAC carrying real-world products such as this BCG, instead of concentrating on big names.

I ordered on a Friday and received the item by Monday. Haven't gotten to use the bcg yet, but it looks great and will definitely be an upgrade to my current bcg.
