Anyone have a good source for a 22 receiver sight (the kind that fit the 3/8" dovetail) at a reasonable price? I've been using a Mendoza brand sight, but it's not very refined (gross understatement) and sits WAY too high which means it doesn't work well with a normal height front sight. I'd like to bring the line of sight back down closer to the bore, if I can find a good candidate.
