ya doable or you can move your front site over if/or it isn't centered my site screws were very dirty so I took them out cleaned and then made my adjustments on my vinny my 8mm was the same.
After I got the gas system set up I did some bench rest shots. Groups are on par with my M1, about 1.5" but just slightly to left of center. I'm assuming the small screws on either side of the rear sight leaf for making fine windage adj, but since I didn't have the correct size screwdriver with me I didn't try. Also didn't see anything on this in the little FN49 manual I had. Any inputs?
