Yeah, I agree with the difficulty mounting a scope on the 392/397 so I went with an aperture sight and that works very well. One of the nice features of those rifles are their size and weight and I really enjoy using mine with iron sights. Three or four pumps for target practice and 5 or 6 pumps for something more serious.
I have a Williams receiver sight on my Blue Streak too. But I don't know if I actually like it better than the barrel mounted notch.
It seems less precise to me. The hole is maybe too big, I don't know. Still works for cans and stuff.
