The Harrier – From Ruger’s New Kentucky Plant

The Ruger Harrier rifles are a completely re-engineered line of modern sporting rifles (MSRs). They represent the latest evolution in AR-pattern rifles. Manufactured at Ruger’s recently acquired Hebron, Kentucky, factory, Harrier rifles are designed to deliver superior fit, function, and aftermarket compatibility.

Initial Harrier rifle offerings include two rifles chambered in 5.56 NATO ( And .223 Remington). Both models feature a rigid, free-floated 15-inch handguard with M-LOK accessory slots. However, they differ in configuration to meet varying shooter preferences. Model 28600 features a mid-length gas system, Magpul MOE-K2 grip, Magpul DT Carbine stock, and a handguard with a full-length STANAG-spec top rail. Model 28601 is equipped with a carbine-length gas system, classic black A2 grip, M4 collapsible stock, and a lighter profile handguard without a full-length top rail.

Forged Upper and Lower


Each Harrier rifle features forged 7075 aluminum upper and lower receivers. They meet mil-spec standards and are finished with Type III hard-coat anodizing for exceptional durability. The lower receiver is equipped with a GI single-stage trigger, safety selector, and trigger guard. It also includes an integrated tension screw that allows users to fine-tune upper-to-lower fitment. A mil-spec diameter carbine buffer tube with a staked castle nut, standard recoil spring, and carbine-weight buffer completes the lower assembly.

Each flat-top upper receiver includes Picatinny rail slots, a forward assist, dust cover, brass deflector, and mil-spec charging handle. The 16.1″ barrels are black-nitride coated for corrosion resistance and longevity. They incorporate 1:8″ twist button rifling, a 5.56 NATO chamber, and 1/2″-28 muzzle threads capped with a classic A2 flash hider.

The bolt carrier group is engineered for reliability. It includes the bolt, carrier, and gas key finished in black nitride.
