Hi. I have a Pedersoli Rocky Mountain Hawken 54 caliber, which has the fancy extended Hawken rear sight, thereby putting the sight closer to my eye. Unfortunately, it's too close for my eyes. I bought a replacement rear sight (3/8") that just sights above the dovetail, instead of extending several inches towards my face. Is there a particular way to remove the factory sight (right to left or vice versa), or doesn't it matter with the Pedersolis. Thanks.
