Price reflects that this is a rare, discontinued item. This the VFC clone of the prototype Remington HK416 rail allegedly used by Devgru in the UBL raid, very cool for impressions/clones and compatible with real 416 uppers. There is a significant ding on the collar where the rail meets the upper but otherwise in great condition. (Can send pics) Includes gas block with no sling loops (will not fit over stock gas block without these removed) and barrel nut, as well as all three rail segments already installed.
