This is the KAC folding rear sight for ranges up to 600 meters. The sight is adjusted for range using the adjustable drum tower and for windage with the windage knob on the side. The sight is meant for use with USGI M4 rifles and their Mil-Spec equivalents. This sight can also be sued with other compatible .223/5.56mm rifles, but the sight adjustments will not be accurate for that rifle and time will need to be taken to find how the adjustments correspond to the rifle. Now that the legal aspect is out of the way. The sight mounted to picatinny MIL-STD-1913 rails and is secured with an adjustment screw and clamp. When not needed the sight folds down out of the way.
25/300 Meter Zero: Place a target 25 meters down range. Turn the rear sight drum to the “Z” setting 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, turn the rear sight drum to the “3” setting and confirm zero at 300 meters.
50/200 Meter Zero: Place a target 50 meters down range. Turn the rear sight drum to the “2” setting 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 200 meters down range and confirm zero.
-Once zeroed by one of the above methods, the rear sight’s 200, 300, 400, 500, and 600 meter range marks may be used for engaging targets at those distances. However, because the range markings are averaged between rifle and carbine barrel lengths, the exact point-of-aim/point-of-impact sight settings may differ a click or two for a given rifle. If possible, fire your rifle at known distances and record your exact + or – clicks for each range. The rear sight’s intermediate clicks between major range markings may also be used to engage targets at ranges such as 250 meters, 375 meters, etc.
