I have an FN Five-SeveN, a gun that does not have an option for factory night sights. I am looking for a local gun smith who can add night sights to my pistol. Places online have a turn around time of 5+ weeks, and I just think that's too long, especially for the $300 price tag associated with it. Anyone know of a gunsmith that can add night sights to my Five-SeveN? It is a Mark II with adjustable sights.
