The Daniel Defense AR10 12.0 Lite Rail was designed to work with the AR10, DPMS, and Rock River Arms LAR-8 .308 rifle length gas systems; but works equally as well mounted over top of a low profile gas block.

The rail and bolt up plate are machined from 6061-T6 aircraft grade aluminum and all fasteners are military specification.

The rail’s unique “Bolt Up” mounting system mates with the upper receiver to create a singular ‘monolithic’ rail along the entire top portion of the rifle. The rail interface not only free-floats the rifle’s barrel for improved accuracy, but also generates huge benefits when mounting optics and accessories.
