I guess they do make 2 MOA dot scopes. That wouldn't be so bad out to 50 yards on small critters. I have never had any dot scope before. Just got a chance to look through one and I liked it. I have never been a fan of pistol scopes because they seem slow to me.
The Nikon Monarch has a 1, 4, 6 or 10 MOA dot. Really handy to be able to change the dot size. The aimpoint is top notch quality, but Nikon is certainly no slouch. I got mine at huntersdiscount web page
