We just received a small batch of the LWM Ni-B BCG.

Leitner-Wise Manufacturing (LWM) has released their new enhanced bolt carrier group. The bolt is a standard, correct weight USGI bolt carrier group that LWM has improved by working on the bolt lugs and radiusing process, and by putting extra tension in the grinding and turning of the bolt so it is more concentric. The entire thing is nickel-boron coated.
