Ruger SFAR | .308 Win | 20″ Barrel | 20rd | MFG# 5611

The Ruger SFAR is a small-frame autoloading rifle chambered for 7.62 NATO / .308 Winchester that retains a modern sporting rifle form factor while providing the ballistics of a larger cartridge. It ships with a free-float 15″ M-LOK handguard, a threaded 20″ cold hammer-forged barrel with 5/8″-24 muzzle threads, and a Magpul MOE SL stock and grip for familiar ergonomics. The rifle includes a Ruger Elite 452 two-stage trigger and is supplied with one 20-round Magpul PMAG.

For optics, a Vortex Viper PST Gen II 1-6×24 (under $1,000) is a practical choice that pairs well with this platform for medium-range work and fast target acquisition.

Recommended uses include medium-range hunting and precision/target shooting where .308 ballistics are appropriate.
