Have not been able to photograph the front sight adequately to share. After more careful examination, it appears to me that the ramp is centrally located on the top of the barrel, but the dovetail and the top of the ramp are off and this tilts the sight blade. When looking through the peep sight of the Williams FP receiver mounted sight you can see the tilt to the left. Also to get the windage adjusted to to near the center (was shooting high and right), the aperture is about three lines to the left of center. The .500 beaded blade sight I installed, seems to aggravate the symptom. I need to go back out and sight it in better for now. The sight blade I bought is incorrect as it is too wide for the ramps width.To confirm my adjustments, should I initially make sure the blade is centered over the ramp and the barrel? Plus my gunsmith is unavailable.
