Ruger's latest addition to their modern sporting rifle lineup, the Small-Frame Autoloading Rifle, or SFAR. Chambered in 7.62 NATO / .308 Win, the SFAR combines the ballistic advantages of .308 Winchester with the size of a traditional MSR. By utilizing superior materials and engineering, the SFAR is bigger and stronger where it needs to be and remains smaller and lighter than comparable .308-sized rifles.
