The AR-Stoner AR-15 Side Charging Upper Receiver assembly chambered in 22 Nosler delivers precision accuracy at an affordable price. The machined billet aluminum upper receiver is combined with an extruded aluminum free float handguard and both are Type III hard coat anodized.
This complete upper features a rifle length gas system for use with 22 Nosler ammo, a mil-spec bolt carrier group, a stainless steel, 18” heavy contour barrel with a lightweight 15” free float AR-Stoner M-Lok handguard and a stainless steel A2 flash hider.
The 22 Nosler's case design takes advantage of the AR-15's modularity, making the conversion from a standard 223 Remington/ 5.56 NATO to the 22 Nosler® simple, requiring only a swap of the upper to the new chambering and switching out to a 6.8 Rem SPC magazine. This effortless two-step retrofit allows shooters to experience the 22 Nosler's performance, while still being able to use their existing 223 bolt carrier group.
Attach your favorite sling to the free float handguard with integrated QD mounts and use the precision M-Lok cutouts at the three, six, and nine o'clock positions for mounting MIL-STD 1913 Picatinny rails or other direct-attach M-Lok accessories.
