Microbest chrome premium bcg
100% satisfied with this bcg and the customer service from ARFTAC. Works great in my S&W M&P 15. Ordered on a Friday and got to my house the next Monday. I'll be ordering a second Microbest chrome premium bcg for my Ruger as soon as one is back in stock. Thanks ARFTAC and Microbest.

The Best Bolt Around
This bolt is a must if you want the best turn key bolt out there. The finish from MICROBEST is the best. Hard Chrome is very hard to find today and the finish is the strongest out there holds lubricity very well. Even the springs come are high quality. If you're looking for a bolt that will last 2 life times this is your bolt!

Chrome BCG is best BCG
Microbest chrome BCG with phosphate extractor and Sprinco 5-coil extra power extractor springs. So far 200 rounds in and it's performed flawlessly. Clean before 1st use, lube properly and it should run well. Can't recommend any other BCG since this one is as close to perfect as possible. SOTAR recommends dimpled cam pins so the cam wears evenly by knowing which direction to reinstall for even wear. Easy fix: use sharpie or oil based marker to write a dot on cam pin so it's reinstalled facing same direction after every cleaning.

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

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.

Fast shipping, great product
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.
