I am interested in buying one of these scopes to replace my mark 4 leupy 6.5-20 but the issue i have is on there web sight it says they only have 46" of elevation and i dont know if that is based like all other scopes.which is from one extreme to the other?if that would be the case the leupy would have double adjustment and the 6.5-20 conquest would have just as much with a 1" tube.the reason i want to upgrade is due to glass quality.what i would gain in glass quality i would loose in adjustment.I shoot to 1000 yds and i think it could be a great scope for the price if it has what i need.
