I recently had the IBA mounts installed on our GA Precision Crusaders. The rifles are equipped with Nightforce 3.5x15x50mm scopes. When I mount the AN-PVS 22 it don't line up with the objective. There is almost a 1/2" height difference with the night scope being higher than the Nightforce. Has anyone had any accuracy issues with this setup? My only recourse is to get higher rings but that would cost my Department $ we don't have. Thanks for the input.
