Rail mounted slide racker?

Does anyone make a slide racker that fits into one of the unused slots on an optics rail? I've seen a number of rackers that fit in the dovetail slot for the rear sight but none that fit the square slots of a rail. Maybe something that mounts like a scope ring or sight mount with one bolt?

Never seen the need. Been using my front ring of the UD for 24 years.

Yep!

When I shot dots, the dot WAS the slide racker.  Use that and/or one of the rings and that should be all you need.

After trying several scopes I have found the best slide racker to be the Aimpoint Comp.

And, which makes me wonder why I have bought a lot more scopes than guns?

Also, when shooting irons, sights were never replaced!
