The highly versatile 200-600 Meter Folding Rear Sight features a finger-adjustable, rotating drum that enables shooters to engage targets from 200 to 600 meters with both speed and accuracy.
The full-sized 600 meter back up iron sight is used on a number of military rifles from the early years of the Global War on Terror (GWOT), perhaps the most notable for military clone rifle enthusiasts is the Mk12 Mod 1.
