ok, I have seen these for decades (some of them), but I never really paid much attention to them. i don't really know what (if any) differences there are between red dots, holographic sights, and reflex sights. and i certainly do not understand the rating that they are using. in a rifle scope, moa means minute of angle. but there is no way anyone would actually spend money on a 65 moa holographic sight, which if i went by rifle scope terminology, i could just point the gun in the general direction and be that good! lol. help bring an olddd dog into the 21st century please!
