Designed with tactical shooters in mind, the XPS2-300 offers a 2-dot ballistic drop reticle that allows the shooter to zero either subsonic or supersonic rounds in the same reticle pattern. Offered in the XPS2 platform, it is the shortest and lightest HWS sight available. Its size and weight make it convenient for hunters, military and law enforcement officers to carry. The single compact lithium 123 battery configuration opens up more space on the rail for rear iron sights or magnifiers.
