The AR-STONER AR-15 Side Charging Upper Receiver Assembly Gen 2 is chambered in .223 Remington Wylde and delivers precision accuracy at an affordable price. The machined billet aluminum upper receiver is combined with an extruded aluminum free float M-LOK handguard and both are hard coat anodized.
This complete upper features a mid-length gas system, bolt carrier group, 18” heavy profile barrel with a matte finish and a lightweight 15” free float AR-Stoner M-LOK handguard and a flash hider.
