Im a ML rookie. Do I have to use a ML scope, like the Leupold Ultimate Slam or Nikons ML scope, for a CVA Acurra? Or can I use a regular rifle scope in 50 mm obj.. Was wondering why I never see 50 mm on MLs. Usually see 40mm or below. All my rifles have 50mm or 56 mm and I am just used to that size. Look forward to learning alot on here. Thanks.
