Very Nicely Machined ProductReview by
I am using this as the basis of a minimalist ultralight upper build using high quality components. This really fits the bill and makes a spectacular fit with both of my Spartan ambi billet lowers. (Posted on 2/17/2017)

Wished the coating was a deeper black but the upper fits and works very well for my 9mm carbine build! (Posted on 8/18/2016)
