Best bolt carrier group? - Watchtower Firearms Durabolt 5.56 Bolt Carrier Group (BCG)

I might never know. This was clearly my first choice after reviewing quite literally, hundreds of bolt carrier groups. Unfortunately, it'll be months before I ever lay hands on one of these. I'm not sure if its the manufacturer not being able to keep up with supply and demand or if it's the fact that you can get one of these F-1's for less than $150 and EVERYONE is out of stock! It's happening with all manufacturers. Finding a bcg today is a next to impossible task. Still, my next build will have to wait for this one. It's truly that good of a bcg.

Fortunately, with the staff at Optics Planet, I was able to find a nickel boron bcg which also is extremely highly rated. They only had a few in stock so I ordered it instead for this build. I won't disclose the manufacturer since it is in competition with F-1 Firearms. But if you ever get the chance at one of these, I would take it in a heart beat.
