The Ruger Harrier 5.56 NATO is a purpose-built modern sporting rifle engineered for shooters who demand reliability, modularity, and practical accuracy in a refined AR-platform package. Chambered in 5.56 NATO and built around forged 7075-T6 aluminum receivers, the Harrier delivers the durability and performance expected from Ruger-without unnecessary complexity. At its core is a 16.1" government-profile barrel with a 1:8 twist rate, optimized to stabilize a wide range of common 5.56 bullet weights. The nitride finish enhances corrosion resistance and service life, while the carbine-length gas system provides consistent cycling across varied ammunition types. Whether you're training, competing, or setting up a dependable defensive rifle, the Harrier offers a balanced blend of performance and value. The rifle ships with a 30-round Magpul PMAG, A2 flash hider (1/2x28 threaded muzzle), and a mil-spec single-stage GI trigger group-keeping the platform familiar and upgrade-ready for experienced AR shooters. The rifle is built around forged 7075-T6 upper and lower receivers machined to mil-spec dimensions and finished in Type III hard coat anodizing for durability under hard use, with an integrated tension screw to reduce receiver play for a tighter, more refined fit. A slim free-float M-LOK handguard enhances accuracy potential and ergonomics, offering versatile accessory mounting at the 3, 6, and 9 o'clock positions, along with Picatinny sections at 12 o'clock for optics or backup sights. A nitrided bolt carrier group with a properly staked gas key ensures dependable cycling and easy maintenance, while the 1/2x28 threaded muzzle, mil-spec buffer tube, and full AR-15 component compatibility provide flexibility for future upgrades. Finished with practical features like an A2-pattern grip, forward assist, dust cover, brass deflector, and QD sling sockets, this rifle is purpose-built for reliable performance in range, field, or defensive roles.
