I did find one for my 10/22 takedown and relatively cheap its a Monstsrum 3x32 prism it has worked out for that application. They run around $80 Decent for a rifle now back to the pistol thing lolI have an astigmatism as well, and the bloom of a red dot sucks. I have a vortex that doesn’t do it to bad, but a Burris I have is terrible for me. I hope you find one that works, I would like to know myself for future purchases.
