Due to its huge 9x zoom ratio the 3-27x56 PM II High Power is perfect for multi-caliber rifles. Although initially developed for and still in use by USSOCOM (United States Special Operations Command) for extreme long-range shooting it has proven to be very versatile: the 3-27x power range and parallax adjustment/side focus going down to 10 m can handle easily anything from a close, quick shot to long-range distances.
