im thinking of a red dot on the 20, not necessary but it would give a better sight picture. but the advantage is so miniscule i don't think it would be worth it.
i've taken all the scopes off my rifles for the same reason.
my vision is 20/15 (with my glasses on!) so its just that i got the right set of lenses and all and the eye doctor told me 20/15 vision with them on.
i always had my scopes set at the lowest magnification which was 4x and even that amount of magnification was unnecessary for me.
so it's all open sights now.
rifle cabinet looks great this way i think, less bulk, and i no longer have to worry about bouncing around the scope on the gun rack behind the truck seat. the windmill companies are slowly replacing alot of logging road on my land so hopefully next season it will be a smooth ride.
