Review by Matt D. on 6 Jan 2022review stating Centurion mid quad rail
I've had several Daniel defense rails. This is My new go to in Block type builds. Super secure and simple to install. Very impressed with quality. Will now buy for a carbine!
Review by Garrett A. on 18 Oct 2019review stating Just what I wanted
This c4 rail is exactly what I wanted. A mid length gas system, front sight base with a little extra room for grip and weapon light. Made very well and securely mounts up to standard barrel nut. Looks great also. I can’t ever see have a issue with this. Rainier Arms is always great to do business with.
