If it’s an original SC from back in the 40s or 50s timeframe with the long tapered front ramp it takes the round topped “Huntsman” hood. The newer ones from the 80s used the new style “widescan” hood and will have a shorter ramp. They aren’t interchangeable as the have a different shaped detent that snaps into the grooves machined in the ramps. The newer style are a dime a dozen, the old style are quite rare.
For you guys using fiber optic fronts and want to use a hood to protect it but not have the fiber shaded. Take a Dremel with a sanding drum and cut a saddle through the center of the hood perpendicular to the axis of the bore. This will leave a hole for light to get to the fiber tube so it “illuminates” but will offer some protection to the fragile insert. Or you may be able to source one of the already spotted hoods that came on the orange sighted M60s and other 22s, they used the same ramps as the centerfire leverguns.
