Recently purchased and I am elated with it! It is extremely accurate and lots of fun at the range. I found an off-set mount through brownells so I can put a scope on it if I ever decide to hunt with it. What I was hard pressed to find, however, was any kind of rear sight upgrade, or diopter sights for this rifle. I searched the swissrifle forums and read their advice, visited the sites they listed and their was nothing. I really like the rifle, at the range at least, to hold to it's roots as an iron sighted rifle. The stock rear sight, as you may well know, is notched very thinly and is extremely challenging to use beyond 150-200 yards for me at least. Does anyone know of a place where a different sight style can be acquired readily?
