KAC’s line of Backup Iron Sights are currently in use by the United States Army, Marine Corps and numerous law enforcement agencies worldwide. Our simple and rugged 300 Meter Folding Rear Sight is more economical than the adjustable 200-600 Meter Rear Sight, and features a fixed post aperture that is ideal for shooters who want an easy to use, close to medium range back-up sighting solution. The 300 Meter 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.
Elevation Adjustable: No
Windage Adjustable: Yes
Place a target 25 meters down range and fire a 3 round group(s). Adjust the front sight post and rear sight windage knob until the desired point-of-aim/point-of-impact is achieved. If possible, place a target 300 meters down range and confirm zero.
