Description
The AR-STONER AR-15 Side Charging Upper Receiver assembly chambered in 450 Bushmaster 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 Type III hard coat anodized.
This complete upper features a mid-length gas system, a mil-spec bolt carrier group, heavy-profile barrel with a parkerized finish and a lightweight 15” free float AR-Stoner M-LOK handguard and a 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.
