Welcome to the GTA Forums Belton,
You have foundTHE GREATEST PLACE TO BE !
As for your scope, You should return the scope, for an A.O. scope, an A.O. scope will focus down to 10 yards, to infinity. The Non A.O. scope will focus at 50 yards too infinity, so it will be blurry when you try to shoot closer than 50 yards. So unless you intend on shooting at 50 yards and greater, the A.O. scope, is the one for you.
So now that you are a member of the GTA Family, I hope to see you here often ! And if you are into pest control or hunting, we have a GREAT Hunting Gate, that would love to your accounts, and photos !
Bill
