We found a SVD on a chopper Crash site on the private Server Oldschooldayz.net . As my friend had no mag for the SVD he gave me the PSO1 scope to mount on the AKM. After looking trough it for a few minutes, we moved foreward while I kept the akm in my hands. My zeroing keys are at mouse button 4 and 5 so that I am not sure if I tryed to zero my gun downwards or if the zeroing went automaticaly from 100 to 50 (you can see it in the video at minute 1:20) . But I noticed that I could zero the akm only up to 300 meters. This was when I noticed that the PSO 1 Scope has disapeared.
