Dd mk18 is all the hype - Daniel Defense MK18 RIII URG 10.3 inch 5.56x45mm NATO Upper Receiver with Flash Hider Assembly

The MK18 RIS III upper from DD is beefy. Unlike many other hand guards, there is virtually no deflection. Fit and finish are what you would expect from DD, very smooth with no machining “grabs” like in lower quality builds. Wasn’t sure how I was going to like the grip-n-rip charging handle, but it’s as good as any other top tier CH. This upper was definitely built for abuse!
