Does anyone make a weaver mount that can replace the rear dovetail for a Kimber fixed sight Stainless 10 II.

I have run across several interesting optical sights at reasonable prices that use weaver bases.  Docters and EOTechs (with Kimber bases) are a bit pricey, and some I see are too cheaply made to stand up to recoil.  I had a chance to take a look at a Hakko and it was impressive, reasonably priced, and seemed well made...but it uses a weaver base.

Perhaps even a frame mount if it wouldn't mar the gun.  I'd like to avoid a "sweat on" or drilling/tapping the frame.
