Rise .22 Arc 18''Bbl 1-7 Twist Complete Upper Dark Gray

The Rise .22 Arc 18" barrel complete upper receiver gives you a dedicated platform for one of the most exciting modern rifle cartridges without breaking the bank or your setup. Built on the AR-15 platform, this upper combines a compact 18-inch stainless steel barrel with the precision and handling characteristics serious .22 Arc shooters want—whether you're building a new rifle, upgrading an existing lower, or stacking together a specialized varmint or competition gun. The dark gray Cerakote finish stands out from standard black while delivering the same durability you'd expect from a complete Rise upper.

The 18-inch barrel features 416R stainless steel construction with button rifling and a 1:7 twist rate optimized for .22 Arc ballistics. A fluted profile keeps weight down without sacrificing rigidity, while the threaded muzzle (1/2"x28) gives you room to add a suppressor or compensator. The barrel has been air-gauged and tested to ensure the accuracy Rise is known for. Backing the barrel is a rifle-length gas system tuned for reliable cycling with this cartridge.

The free-floating skeletonized handguard runs 15.25 inches and includes continuous Picatinny rail along the top for optics mounting, M-LOK slots for accessories, and four threaded steel QD sling attachment points—all wrapped in a snag-free design. The forged billet aluminum receiver and premium bolt carrier group (featuring a 9310 bolt, individually MPI tested, with staked gas key and black nitride finish) round out a upper that won't leave you guessing about quality. An ambidextrous charging handle means lefties and right-handers alike can operate it smoothly, even with gloves or an optic in the way.
