Almost any of the low mount red dots work on the 10-22. If you want a fast reticle and some magnification, look at the Konus shotgun scopes, They are parallax-ed at 75 yds and available at SWFA. The 2.5x32 runs $45 and the 1.5-4x32 is about $80. Fully coated, etched reticle in a diamond pattern. I have a couple of the 2.5x32s.
