I have a Zastava 9.3x62 that needs some new sights. ( both front and rear) I would like to order a set from New England Custom guns, but am not quite sure how to measure the barrel radius. They have the formula on their website to figure sight height, but I cant find anything on getting the radius. Do I just measure the diameter at the point where the sight will sit ? Also I see that their classic sights use only one screw, does anyone know how strong they are? This is my guide rifle so it sees some abuse. Thanks
