The Daniel Defense AR15 Lite RailTM 12.0 is the next advancement in the free float rail systems. The AR15 Lite RailTM 12.0 FSP weighs in at only 14 ounces and utilizes a steel barrel nut! The Patent Pending bolt up design allows for an uninterrupted upper rail platform.

The Daniel Defense 12.0 FSP Free Float Rail System features an opening in the top rail to accommodate the front sight post and gas block of a carbine length AR15 gas system. This precision cut-out provides much needed rail space along the top, sides, and bottom rails of the 12.0 FSP. The rifle’s front sight post protrudes through this opening but does not diminish the useable mounting area on the rail that extends beyond the gas block and over the carbine’s barrel. This extra “real-estate” is a perfect location for aiming devices, flashlights, and laser sights.

Rails are 1913 Mil-Spec and are 100% checked for conformity. Every rail includes your choice of ladders or panels, which are made from santoprene, which can handle heat up to 350 degrees.
