i have 4-12x40Ao simmons prohunter on mine. i thinks its nice scope for hunting. alot of people go for over 16x just so when there punching paper they can see the bullet holes on the target with out using a spotting scope.
which rifle do you have?
if it has a heavy barrel i like the look of 40mm Obj just so the barrel andthe scope dont look the same size.
