The Ruger Mini-14 Ranch 5817 delivers proven semi-automatic performance in 5.56x45mm NATO with enhanced corrosion resistance and modern optics compatibility. This stainless steel variant combines the reliable gas-operated action of the classic Mini-14 platform with contemporary features that extend its versatility across multiple shooting disciplines.

What Makes This Different

The matte stainless steel construction provides superior weather resistance compared to standard blued finishes, making this rifle suitable for harsh environmental conditions. The integral scope mount system eliminates the need for aftermarket rail systems, while the 18.5-inch barrel length strikes an optimal balance between velocity retention and maneuverability. Factory-drilled and tapped receiver accepts standard Weaver-style rings directly.

Key Features

  • Matte stainless steel barrel and action resist corrosion and environmental wear
  • 18.5-inch barrel optimized for 5.56 NATO ballistics with 1:9 twist rate
  • Integral scope mount bases eliminate need for gunsmithing modifications
  • Black synthetic stock provides lightweight durability and weather resistance
  • 20-round detachable magazine with reliable feeding geometry
  • Protected post front sight and adjustable aperture rear sight system
  • Cold hammer-forged barrel ensures consistent accuracy and extended service life
Field performance centers on the proven gas-operated action that cycles reliably with both military surplus and commercial ammunition. The 5.56 NATO chamber specification handles both .223 Remington and 5.56 NATO loads safely, providing ammunition flexibility for training, hunting, and competitive shooting. Stainless steel construction maintains accuracy potential in humid conditions where carbon steel alternatives might suffer degradation.
