The innovative Daniel Defense AR15 Lite Rail 12.0 system gives the weapon system an uninterrupted upper rail platform and also allows the Armorer to install the rail system with simplified alignment to the upper receiver. Not only does this battle proven system provide features that no other rail system possesses, but it is also the lightest rail system available.
