KAC's line of Micro Iron Sights are currently in use by the United States Army, Marine Corps and numerous law enforcement agencies worldwide. So many places have chosen the KAC BUIS because of their exacting tolerances and ability to maintain zero under very adverse conditions. More economical than the adjustable 200-600 meter micro rear sight, the fixed post aperture of the 300 meter micro rear sight is ideal for shooters who want an easy to use, close to medium range back-up sighting solution. The 300 Meter Micro Rear Sight is adjustable for windage only, and includes a snap-in polymer aperture insert that gives the user a more precise sight picture if desired. When zeroing for 300 meters it is easiest to start at 25 meters. It is very important that you verify at 300 meters after sighting in at 25.
