Ruger Mini-14 Tactical 5.56 NATO Semi-Automatic Rifle | 16.12" Threaded Barrel, Speckled Brown Hardwood Stock
The Ruger Mini-14 Tactical Model 5889 pairs the platform’s proven short-stroke gas system with a compact 16.12-inch cold-hammer-forged barrel and factory 1/2-28 threads. Serial prefix 585 denotes the post-580 tapered-barrel redesign, and this variant’s speckled brown hardwood stock was offered only on this SKU. Combined with integral scope-mount cuts and reliable ghost-ring sights, the rifle delivers a versatile package ready for optics, suppressors, or iron-sight use.

The 16.12-inch alloy-steel barrel is cold-hammer-forged for durability and cut with a 1:9 RH twist suitable for common 55- to 69-grain 5.56 NATO loads. A factory-installed bird-cage flash suppressor caps the 1/2-28 threaded muzzle, giving the buyer ready compatibility with most AR-pattern devices and suppressors.
Ruger’s fixed-piston, rotating-bolt action keeps fouling out of the receiver and provides consistent reliability. The vented steel upper handguard acts as a heat shield, allowing extended strings of fire without overheating the forend.
Integral scope-mount cuts in the receiver let shooters add Ruger rings (not included) without additional bases, while protected blade front and ghost-ring rear sights give a clear, fast sight picture right out of the box.
The speckled brown hardwood stock offers a straight-comb profile and a 13.62-inch length of pull, balancing classic appearance with practical ergonomics. At 10-round capacity (with included magazines) and a 10+1 firing setup, the rifle suits sporting, ranch, and defensive roles.
