I wouldn`t use anything else for longrange shooting... The target turrets are great and each click is both audible and has a possitive feel to it when dialing in.. I have a 5.5-22x 50 on my 223 and its there to stay.
As Remmy said there are brighter scopes such as s&b,sworo,ect but as far as durability and reliabily goes.. The nightforce is the go....
