I'm looking @ one of the MK4 ER/T scopes with the 34mm tube. Is the windage turret ridiculously tall/big or is it just me. I someone has one of these MK4's would you mind giving me the width and height of the windage turret. Can it be replaced with a shorter turret? How would the MK4 ER/T compare to the MK6 ? Your opinion of the scope would be appreciated. By the way , I know it is an old scope. Thanks in advance.
