So today I went shopping locally for a new lower, I got the itch to build another AR. I walked away with a complete matching billet and lower set. The Nib-X treatment looks flawless. The upper and lower fit are seamless. The lower even has a set screw feature that allows even less upper/lower wiggle. Even though it isn’t needed. I’m very happy with my purchase.
