Ruger SFAR 5611 308 Winchester 20" Heavy Barrel 20+1 Rounds

The Ruger SFAR 5611 delivers precision long-range performance in a lightweight AR-10 platform chambered in 308 Winchester. This rifle combines Ruger's engineering expertise with premium components to create a versatile precision rifle suitable for competition shooting, hunting, and tactical applications.

What Makes This Different

The SFAR (Small Frame Autoloading Rifle) architecture reduces overall weight by 1.5-2 pounds compared to traditional large-frame AR rifles while maintaining full 308 Winchester power. The 20-inch heavy barrel profile provides enhanced accuracy and velocity retention at extended ranges. Ruger's two-part Heavy Boomer muzzle brake significantly reduces felt recoil and muzzle rise, allowing for faster follow-up shots during rapid-fire sequences.

Key Features

• 20-inch threaded heavy barrel with 5/8x24 threads for suppressor compatibility
• Two-part Heavy Boomer muzzle brake for superior recoil management
• Hard coat anodized 7075-T6 aluminum receiver for corrosion resistance
• 15-inch M-LOK handguard with full-length top rail for optics mounting
• Magpul SL synthetic stock and grip for enhanced ergonomics
• 20+1 round capacity with included Magpul PMAG magazine
• Ambidextrous safety selector and magazine release

The rifle's accuracy potential reaches sub-MOA groups with premium ammunition, making it effective for precision shooting out to 800+ yards. The M-LOK attachment system accommodates bipods, lights, and other accessories without adding unnecessary weight. Weather-resistant finishes and materials ensure reliable function in adverse conditions, from humid hunting environments to dusty competition ranges.
