Feyachi RS-38 Reflex Sight Zero Calibration
Select the reticle you desire by turning the reticle selector knob and setting your intensity at the best position. With the sight mounted, rest the gun on a solid support and aim at a target 50 to 100 yards away. Test shots should be done in the same conditions to achieve maximum accuracy for adjustment, for which the use of firm rest for firing and same type of cartridge is recommendable. Each click adjustment moves the point of impact by 1 MOA (approximately 1"± at 100 yds, 1/2"± at 50 yards)
