I run the NiB in multiple rifles and pistols. A big performance factor for me is ease of cleaning. I do custom cerakote as well and I’ve noticed that the NiB/cerakoted upper receiver combo is a win for reducing carbon build up which helps with performance. Honesty a paper towel with some CLP is all I use to wipe out my receiver and the BCG and it works like a charm. I’ve also noticed smoother cycling and operation with the NiB.

The only thing I dont run NiB in is if my .300 BLK pistol. And thats only because it doesnt like to cycle subs.
