These modified Russian Saiga rear sights provide a clearer sight picture and faster target acquisition. Meant for 1000m rifles. These are marked for 1, 2, and 300 meters. They will also work on 800m rifles, but the meter setting will not be correct. Between different ammo makers specs vary and sight adjustment is usually ineffective anyway.
Sight is fully adjustable for close quarter situations.
Compare this sight with a standard one side by side and the difference will be like night and day!
