KAC Free Float Rifle RAS (MK 12 MOD 1), 5.56, W/ Three 11-Rib Panels
This is the same rail used by the U.S. Military for their Mk12 Mod1 SPR rifles.
The KAC Free Float RAS (Rail Adapter System) features full length mil-spec M1913 Picatinny rails at the 12-, 3-, 6-, and 9 o’clock positions, making it compatible with any number of rail-mounted tactical accessories. The rail free floats the barrel, allowing for consistent barrel harmonics upon firing, and thus increased accuracy potential. Includes three KAC 11 Rib Rail Panels.
