Helpful Positive Review Easy to clean, Coyote matches Aero's FDE by Nick, Verified Owner, May 31, 2023

Helpful Positive Review Smooth, reliable Nib-X BCG by Steve, February 2, 2022
It runs great so far on my 16" barrel AR, mid-length gas system. Quality components, the Nib-X coating is slick and supposedly can run dry but occasionally I hand coated it with some Hoppe's just for safe measure. Easy to clean and I'll be sticking ...
