16" 458 Socom AR-15 Upper Assembly | Tromix | 1x14 CMV GunKote Carbine Length HBAR Barrel | Compensator | 15" MLOK Rail
Beyond being just another big-bore option, the .458 SOCOM is a specialized powerhouse for the AR-15 platform that delivers the punishing terminal impact of a 45-70 in a modern semi-auto. This system thrives with massive, hard-hitting projectiles, specifically tuned for 300gr to 500gr loads to provide unrivaled versatility for both supersonic hunting and subsonic suppression. If you're building a dedicated hog-stopper or a heavy-hitting brush gun, a .458 SOCOM upper assembly offers the extreme kinetic energy and reliable feeding required to push the limits of the small-bore gas gun.
Ballistic Barn uppers are American Made and machined by manufacturers of mil-spec AR-15 components. All barrels are individually checked for headspace using Manson go and no-go gauges.
