The EZ CAR™ Rail is the perfect drop in replacement for your plastic hand guards. The EZ CAR™ Rail from Daniel Defense has been engineered to offer a rock solid mounting platform for all your AR accessories. The EZ CAR™ Rail easily replaces factory installed plastic hand guards, and it offers a Mil-Spec quad rail that installs in seconds. As simple to install as a traditional hand guard, the EZ CAR™ Rail mounts to a standard delta ring and hand-guard cap of a carbine length gas system with no modifications to the host weapon.
