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. The bolt carrier assembly features a chrome-lined 8620 steel bolt carrier and nitride-processed gas key staked in place. The titanium firing pin has been DLC-coated for long service life.
