Zeroing Tips
25/300 Meter Zero: Place a target at 25 meters and set the rear sight drum to “Z.” Fire a 3‑round group and adjust the front sight post and windage until POA/POI match. Confirm at 300 meters on “3” if possible.
50/200 Meter Zero: Place a target at 50 meters and set the rear sight drum to “2.” Fire a 3‑round group and adjust the front sight and windage until POA/POI match. Confirm at 200 meters if possible.
Note: Once zeroed, use the rear sight’s 200–600 m markings to engage targets. Exact POA/POI may vary by rifle, so confirm at known distances. Intermediate clicks allow engagement at ranges like 250 m or 375 m.
