The AR-STONER AR-15 Side Charging Upper Receiver assembly 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 carbine gas system, a mil-spec bolt carrier group, 16” heavy profile barrel with a Phosphate finish and a Ultralight free float AR-Stoner M-Lok handguard and an A2 flash hider.
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.
