These are about the best hi-caps you can get for the 10/22.

You can actually take these ones apart and clean them. The only other ones I'd even bother with in hi-caps is the Butler Creek Steel Lips, but they are usually aren't much cheaper than the Tactical Innovations ones. TI also has one made out of machined aluminum, but it is a bit more than I care to spend on a .22.
