The cold hammer-forged alloy-steel barrel is threaded 1/2-28 and capped with a Ruger six-slot flash suppressor, giving the shooter immediate muzzle device compatibility without aftermarket work.
An 11" free-float 6061-T6 aluminum M-LOK handguard with an uninterrupted top Picatinny rail provides ample space for optics, lights, and other accessories while maintaining barrel rigidity for consistent accuracy.
Both upper and lower receivers are forged from 7075-T6 aluminum and finished with a Type III hard-coat anodized matte black treatment, offering strength, corrosion resistance, and visual continuity with the handguard and stock.
The rifle’s direct-impingement action, six-position collapsible synthetic stock, and Ruger-branded charging handle keep handling familiar to AR-15 users while adding Ruger-specific touches. The optics-ready flat-top upper lets owners mount their preferred sighting system immediately.
Serial prefix 859 confirms production at Ruger’s Mayodan, North Carolina facility, and the rifle carries a factory MSRP of $1,039.
