Has anyone used an Adams Arms XLP system with a Noveske NSR rail? I've bought the rail but don’t have it in-hand yet. From the pics I'm worried about the barrel nut preventing proper alignment of the drive rod. I went with the NSR because it comes in 16.7" and is super lightweight. If this rail won't work with the XLP does anyone know of any other 15"+ rails that are proven to work with the piston system?
