I have used them all and leupold seem to be the worst of the bunch. why do people insist on thinking that leupold is superior? When it comes to low light conditions they are.....the worst. when it comes to clarity they are .......the worst. Please look at all high end scopes in all companys before overpaying for leupold. Have extra money? You must if you own a leupold, please IM me and I will give you my paypal account # I will take your cash.
