I have a NIB Simmons model #851133 30 mm red dot scope that has 3 dots on the reticle. It has a 11 level reticle intensity control with black matte finish and a mounting rail for 3/8" weaver style base. It is listed as a Crossbow scope but I believe that it might work well on a .22 rifle. The dots are stacked on top of each other for elevation changes, which makes me think that it might work well on a .22 at different distances. I have not tried this as of yet, but once I change my scope mount to a 3/8" base I will try it and post the results. $18 for the scope and $5 for S&H.
