The Daniel Defense AR15 Lite Rail is manufactured from precision machined 6061 T6 aluminum and finished in a hard coat type 3 mil-spec anodized black. It utilizes the Bolt Up System which allows the upper receiver to have a continuous uninterrupted upper rail platform. The Daniel Defense 9.5 FSP Free Float Rail System features a cut in the front of the top rail to accommodate the front sight post and gas block of a carbine length AR15 gas system, while at the same time, providing much needed additional rail space along the sides and bottom rails. Every rail is available with either ladders or panels which are made from cantoprene, which can handle heat up to 350.
