Product Overview
The AR STONER LR-308 Side Charging Upper Receiver assembly chambered in 308 Winchester 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 matte finished.
This complete upper features a rifle-length gas system, bolt carrier group, SOCOM barrel with a stainless finish and an ultralight 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.
