    The Centurion Arms stripped lower receiver that I just obtained from Rooftop Defense looks as perfect as any manmade object can look! There are no visible flaws anywhere and the anodizing and smooth workpersonship is as good as it gets! And the quick response and service from Rooftop Defense can’t be beat!

    Smooth transaction from purchase to delivery to my FFL. Very impressed with the Centurion C4 lower. Excellent quality and is well made. Looking forward to completing my project. Thank you!

    Just picked this Centurion CM4 lower up from my FFL today. I like it a lot. The finish is very, very well done–better than finishes from other companies. It feels very smooth the touch, no tooling marks and a rich, black finish. Also, the Centurion logo is not huge and plastered all over the lower, which I like. Great receiver. Of course Rooftop’s service was impeccable and efficient. Great place to do your firearms-related business!

    Ordered two and got successional serial numbers, which is pretty cool. Solid lowers with very nice annodizing. No big dumb logos that catch your attention which I like. Very useful for my M16A4 “clone” rifle.
