18" 458 SOCOM Shaw Stainless Heavy Barrel AR15 Upper Receiver with 15" Rail and Competition Muzzle Brake
The .458 SOCOM was designed for a single purpose - keep special operators alive by killing their adversaries more efficiently. This is achieved through a high pressure cartridge and a large caliber, 300-500 grain bullet. The result is a round that delivers similar ballistics and stopping power to the much larger .45-70 round on the AR15 platform. We recommend single stack magazines for reliability and our bolts are specially designed to eliminate feeding issues.
