About This Firearm

The Ruger SFAR is a small-frame semi-automatic .308 Winchester built for hunting and range use. Ruger no longer makes it, so it is a used buy. Ruger built it to the size of a 5.56 AR, and at 6.80 lbs it carries like one.

One 20-round Magpul PMAG came with it, and the gas block is a four-position rotary regulator with the wrench for it carried on the rifle, so gas can be turned down for a suppressor. The Elite 452 two-stage trigger breaks at 4.5 lbs. The top of the receiver is Picatinny and the fore-end is M-LOK, with no sights fitted. The Boomer brake unscrews from a 5/8-24 thread that takes other brakes, flash hiders and suppressor mounts.

If you’re cross-shopping, the Sig Sauer 716i Tread has an MSRP of $1,519.99 and weighs 8.50 lbs on a direct-impingement gas system with a single-stage trigger. The Smith & Wesson M&P 10 Sport Optics Ready has an MSRP of $1,259 at 8.00 lbs, with an ambidextrous safety, magazine release and bolt release. Both are more than 1.2 lbs heavier than the Ruger.

Best For

GOOD
Hunting (Deer/Elk)
37.25 inches overall on a 16.1-inch barrel is short for a .308 semi-automatic, so it comes out of a blind or a truck without a fight.
GOOD
Range/Target
The bolt and barrel extensions are CNC-machined from a high-strength super alloy steel with tapered lug geometry, which Ruger did to strengthen the breech for a short-action cartridge in a small frame.
FAIR
Long Range/Precision
The barrel is short and the trigger is a field pull, so a precision build out of this rifle starts with a longer barrel.

Strengths & Limitations

Strengths
  • It takes most mil-spec MSR trigger groups, receiver end plates, charging handles, pistol grips and adjustable stocks, so AR-15 parts carry over.
  • The barrel is chrome-moly with a black nitride finish, under a Type III hard-coat anodized receiver.
  • The gas-regulator wrench rides on the rifle, so the tool stays with the rifle.
Limitations
  • There are no sights, so the rail is as far as Ruger took the aiming system.
  • A two-port brake throws its blast sideways, so the next bench along gets a share of it.
  • Ruger has stopped making the rifle, so it is worth checking that a used one still has its on-board wrench and its Boomer brake.
