A true Small-Frame Autoloading Rifle, the SFAR is nearly identical in size to a traditional 5.56-caliber modern sporting rifle. Chambered in 7.62 NATO / .308 Win., the SFAR combines the ballistic advantages of .308 Winchester with the size of a traditional MSR. Bolt and barrel extensions are CNC-machined from high-strength super alloy steel that outperforms traditional C158 bolts. Tapered lug geometry further strengthens the breech to support larger short-action cartridges.
