The .308 cal. version of the 4-rail free float tube features a solid one-piece free float tube made from 6066-T6 aircraft aluminum. The picatinny style rails are integrally machined into the free float tube, available in "High" for the original LR-308 upper receiver. The free float tubes are vented and hard coat anodized per mil spec and are matte black in color. Overall width dimension is 2.1" only slightly wider than the AR free float tubes, and includes a manganese phosphated steel locking collar to control the timing of the rails.
This item is designed to fit all DPMS standard length 308 models with a smooth sided upper receiver. If you add this to a carbine gas system or a mid length gas system it will need to be modified to be able to set the set screws in the gas block
