This program had a specific requirement to free float an M203 grenade launcher without additional parts, and Daniel Defense delivered. The RIS II itself features four picatinny rails in the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions with plenty of space to mount accessories such as tactical lights/lasers, fore-grips, iron sights, and optics.
