Ruger Harrier 5.56 16.1″ AR-15 Barrel 30-Rounds w/ Magpul Furniture

Built to run with familiar mil-spec controls, the Ruger Harrier 5.56 NATO ships with a single-stage GI trigger, selector, charging handle, carbine buffer, and spring for proven reliability. The upper receiver includes a forward assist, dust cover, and brass deflector, while the lower receiver adds a tension screw to reduce play between the receivers for a tighter overall feel. A nitrided bolt and bolt carrier group with a staked gas key reinforces long-term function in a 5.56 NATO AR-15 rifle designed for consistent cycling.

The free float handguard features a full-length Picatinny rail along the top and QD sling sockets on both sides for flexible setup options. Magpul M-LOK accessory attachment slots run along the 3:00, 6:00, and 9:00 positions, with eight intermediate slots toward the muzzle end to support lights, grips, and other mission-ready add-ons. The 16.1″ government profile barrel uses a nitrided finish and 1:8″ RH twist rifling, and the 1/2″-28 threaded muzzle is fitted with a removable A2 flash hider to support alternate muzzle devices.
