i bought my wasr 10 a few weeks back and went to the range. i notice i was hitting where to the left after changing distance from sighting in. just a few days ago i came across a thread about "watch out for canted sights" made me check mines and yes it is slightly off center by a few degrees, something i would not trust on when making a precise shot. i tapped the two pins on the sight out but cant get it to move. seems the sight is welded to the muzzle.... how can i fix this problem??
