The Nightforce 5.5-22x50mm riflescope was originally designed to give military and competition shooters a large amount of magnification range. The 50mm objective allows for more diverse mounting options where a larger diameter would be a hindrance. The excellent glass provides shooters with crisp images and excellent colors throughout the magnification range and targets at any distance. The 5.5-22x50mm riflescope is at home in extreme long range competitions and on your larger calibers.
