I have never owned a red dot sight and at age 65 my eyes have a-lot of trouble with iron sights.Im use to very good scopes and don't want to start buying red dots that are not top tier.I will be using the red dot on a home defense rifle and I want to keep it light weight.What are your opinions on the Aimpoint T2 and H2.I have looked at youtube reviews on the T2 and H2 and most of them are very positive,Im just looking for advise from shooters who have used them. Thanks
