The AR-STONER LR-308 Side Charging Upper Receiver assembly chambered in 6.5 Creedmoor 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 heavy barrel with nitride finish and a lightweight 15” free float AR-Stoner M-LOK handguard and a flash hider. This Slick Side upper has no forward assist or dust cover.
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.
