I just received the Williams Gunsight 2007 catalog, and I found they have an EXTREMELY cool new set of custom-designed target sights for the 10/22. I'd love to give you a picture, but their website is not yet caught up with their catalog, and the sights aren't available yet anyway.
Recently, I went through a real search trying to find some quality target sights to mount on a 10/22. You can find them galore for guns like Anschutz, but since the 10/22 (until recently) has been regarded by the snobby highbrow crowd as a "lowly plinker" rifle ONLY, it's been hard to find good target-quality sights that fit the rifle without a lot of expensive customization. Recently I customized my own 10/22, and got some Williams FP sights mounted, and it was indeed a hassle: I had to get my new bull barrel drilled, Williams had to calculate front-rear sight heights so I knew what to get, they had to mount a shotgun ramp on the front (because nothing else they had would fit the bull 10/22 barrel), and the receiver had to be drilled/tapped for the rear sight, plus I had to mortice the stock to get it to fit. A lot of work, but it was worth it! Here are pics:

But now I guess Williams has been getting enough demand that they developed true target sights for the 10/22. This is a GREAT development: presumably they wouldn't bother doing this if they weren't getting a lot of requests, and this in turn suggests the 10/22, with all the accurizations and mods people are doing to it, is coming into its own as a true, competitive target rifle. The highbrow crowd doesn't like it, but when I look at the results I can get out of my 10/22 now, and when I hear what many of you can get, the fact is, many of our 10/22's CAN in fact compete in a target competition with all but the super-expensive, super-specialized .22's that cost thousands of dollars. A 10/22 can now be a highly accurate target rifle, competitive with bolt actions such as Coopers that cost 6 or 7 times as much!!!
Anyway, the rear sight is similar to Williams existing FP series, like the one mounted on my gun above, but they designed it carefully so you'll no longer have to mortice your stock to make it fit. You will have to drill the receiver, but that's quick and easy work for any smith. The rear sight sits up pleasantly high enough that you don't have to twist your head sideways to see through it, even with the low line-of-sights 10/22 stock, and it has a beautiful, wide target ring with a tiny aperture hole, just like the Anschutz. And like all FP-series rear sights, it has micrometer-level windage and elevation adjustments, with target knobs, so you can easily make really fine grained setting changes.
The front sight is even cooler. It's one of those globe-style sights, with an interchangeable set of inserts to give you all kinds of different sight pictures: wide crosshairs, fine crosshairs, dots, etc. Compare it to a Lyman or Anschutz front globe sight. For instance, scroll down on this page a bit to see the different inserts offered with the Lyman globe sights. The Williams offerings will be comparable:
If there's a downside to this set, it is cost: $133 from Williams, plus you have to have holes drilled in your barrel to mount the front globe sight, and in your receiver to mount the rear sight. Time all is said and done, you'll probably spend darn near the cost of a new 10/22 to get these sights mounted. But hey, if you're serious about target shooting, this will be an extremely nice option!
