Designed and built in Austria, the Strasser RS 14 Evolution straight-pull bolt-action rifle utilizes a radial element bolt that requires zero rotation of the body to function. The system features interchangeable bolt faces and barrels to accommodate up to 22 different caliber configurations from .223 Remington to .375 Ruger, and only two tools are needed to change calibers, both of which are contained within the gun. The one-piece aluminum receiver sports an integral Picatinny rail for mounting optics. Learn more about it in the video embedded above, hosted by Editor in Chief Scott Olmsted.
