This 580-Series Mini-14 (585-prefix) is a recent-production example made in the USA with a stainless/satin receiver and an 18.5 in tapered stainless barrel. The barrel’s plain crown and the rifle’s short-stroke gas piston with rotating bolt deliver the familiar Mini-14 operating system in a corrosion-resistant stainless package.
The factory integral Ruger scope-ring dovetails are present, and this rifle includes the OEM scope mount and a pair of stainless size 5 rings. The installed Samson full-length aluminum optics rail/handguard provides continuous Picatinny rail space while replacing the factory upper handguard.
The stainless tubular side-folding stock locks in place and features a polymer pistol grip and a 13.5 in length of pull. Iron sights consist of a protected blade front sight and a ghost-ring aperture rear sight.
Chambered in 5.56mm NATO with a 20+1 capacity, this configuration comes well-equipped for range use with three 20-round magazines and two 5-round magazines included.
