Anyone have any experience with these, such as the Williams WGRS aperture or the similar product from Marbles which mount in the same location as a regular open rear sight? Yes, a rear-mounted aperture sight is preferable but in this case I'd like to retain the sleek lines of the rifle.
 
I think they're a bad idea, though some people seem to like them. The principal of the peep sight, (that you look through it, and not at it), requires it to be mounted as close to the eye as possible. Having it mounted out on the barrel means that it's no better than the open sights, worse in my opinion, since it blocks out more of the target and you have a tiny little hole that you're trying to centre the foresight in.
 
Works for me. On my BSA CF2 there isn't really much to mount a sight on at the back of the receiver when a scope is mounted. My foresight is hooded (and it's a Williams Firesight, too) and I see it inside the WGRS ring flanked by its two green dots and all of that concentric in the larger ring of the foresight hood.
 
Ya it works. You need to use a larger aperture for longer eye relief if you want to avoid the same experience 9.3Mauser had. Mounted close to the eye is far better but with the right aperture it is still much better than open sights.
 
About what I expected- some "yea" and some "nay."

The rifle in this case is a Martini Cadet I've just had rebored to .357 Mag. I'm replacing the front sight with a flat-topped blade on a ramp. I can re-shape the rear notch from a "v" to a square notch, which will probably help as well but I'll cobble a large aperture together and try it.

I have an old Lyman 60 aperture sight on hand which would be ideal if the barrel-mounted aperture doesn't work out.
