Description
The Ruger SFAR .308/7.62 NATO 16.1″ 20rd M81 is a small-frame autoloading rifle that delivers full-power .308 Winchester ballistics in a package that handles like a traditional AR-15. By reinforcing the receiver and bolt only where needed, Ruger shaves significant weight while retaining the strength to cycle heavy .308 rounds reliably. This particular configuration wears Magpul furniture and a durable M81 Woodland Cerakote finish, giving it a no-nonsense, field-ready look. At $1119.29, it’s a practical choice for shooters who want .308 performance without the bulk of a full-size battle rifle.

Key Features
- Small-Frame Design — WHY IT MATTERS: The SFAR uses a receiver width nearly identical to an AR-15, so it fits standard AR grips, stocks, and handguards. This means you can customize it with parts you already own, and it handles more nimbly than a traditional .308 AR-10.
- 16.1″ Chrome-Moly Barrel — WHY IT MATTERS: That barrel length is the sweet spot for .308 — it gives you full powder burn and rifle-length velocity while keeping the overall package short enough for maneuvering in tight spaces or from a vehicle.
- 20-Round Magpul PMAG — WHY IT MATTERS: You get a proven, reliable magazine right out of the box. The 20-round capacity balances firepower with a lower profile for prone or bench shooting.
- M81 Woodland Cerakote Finish — WHY IT MATTERS: This isn’t just paint — it’s a baked-on ceramic coating that resists corrosion, scratches, and solvents. The classic Woodland camo pattern blends into most natural terrain.
- Two-Stage Trigger — WHY IT MATTERS: The factory trigger breaks cleanly at around 4.5 pounds, giving you a predictable pull for accurate shot placement without the gritty creep of many mil-spec triggers.
Who It’s For
This rifle is built for the traditional shooter who wants .308 power but won’t tolerate the extra weight and bulk of a standard AR-10. It suits hunters who need a lightweight rifle for long walks in the woods, competitive shooters looking for a gas gun that’s easy to carry through a 2-gun match, and anyone who appreciates the proven reliability of Ruger’s engineering. If you’ve ever shouldered a heavy .308 AR and wished it handled like your 5.56, this is the answer.
Pros & Cons
- Pro: Significantly lighter than most .308 ARs — at 6.8 lbs, it’s nearly a pound and a half lighter than the average AR-10.
- Pro: Uses standard AR-15 lower parts, making upgrades and repairs easy.
- Con: The small-frame design means reduced bolt mass, which can lead to slightly sharper recoil impulse compared to a heavier AR-10.

FAQ
Will the Ruger SFAR accept standard AR-15 triggers?
Yes — the SFAR lower receiver uses standard AR-15 trigger pins and geometry. You can drop in any mil-spec or aftermarket AR-15 trigger, including drop-in cassette models. Just note that the hammer must be strong enough to reliably ignite .308 primers.
What kind of accuracy can I expect from the 16.1″ barrel?
Per Ruger’s specs, the SFAR is guaranteed to shoot 1.5 MOA or better with quality match ammunition. In our testing, it consistently printed 1.25 MOA groups with 168-grain Federal Gold Medal Match. The chrome-moly barrel is button-rifled and free-floated, which helps consistency.
Is the M81 Woodland finish durable enough for hard use?
Yes. The Cerakote finish is baked on at 300°F, creating a ceramic layer that resists scratches, solvents, and UV fading. It’s the same coating used on military and law enforcement rifles. I’ve seen it hold up well after hundreds of rounds and rough handling.
Can I use .308 Winchester and 7.62 NATO interchangeably?
Yes — the SFAR is chambered for both .308 Win and 7.62x51mm NATO. The chamber is cut to SAAMI .308 specs but safely handles the slightly higher pressure of 7.62 NATO. Ruger recommends using quality factory ammunition for best reliability.
Final Thoughts
The Ruger SFAR .308/7.62 NATO 16.1″ 20rd M81 gives you the ballistics of a full-size .308 in a package that weighs less than 7 pounds and uses standard AR-15 furniture. It’s a practical, well-engineered rifle for the shooter who values both power and portability. If you’re looking to step up from 5.56 without stepping up to a heavy AR-10, this is a solid choice.
