If I started another 11.5" project, this is what I would use and order it with a URX 4 from the get go and be done.
My other 11.5" projects have consisted of DD or Noveske 11.5" with factory pinned gas blocks or Colt 11.5" barrels with shaved FSB. None of these projects I have been completely satisfied with.
1. The DD barrel is overgassed
2. The Noveske barrel is a heavy socom type contour but otherwise ok
3. The Colt with shaved FSB will not fit under most slim rails.
I had to use a 10" KMR which I am not happy with. I would rather have a Noveske NSR, but they don't make it in 10" length to cover a 11.5" barrel.
The KAC 11.5" upper has everything ready to go. URX 4 with 7 sides in 10" length rail and no gunsmithing required.
