Black Rain Ordnance SPEC15 Upper Receiver .458 SOCOM 16" – AR-15 Compatible

The Black Rain Ordnance SPEC15 complete upper receiver chambered in .458 SOCOM delivers serious stopping power in a compact 16-inch configuration. This upper is designed to drop onto any mil-spec AR-15 lower receiver, converting your platform to handle the hard-hitting .458 SOCOM cartridge for close-range hunting or defensive applications. The 16-inch barrel keeps the overall length manageable while maintaining the velocity needed for effective terminal performance within typical .458 SOCOM engagement ranges.

Constructed from forged 7075-T6 aluminum with Black Rain Ordnance's proprietary black finish, this upper features a full-length rail system for mounting optics and accessories. The upper comes fully assembled and ready to install—no additional parts or modifications required to mate with your AR-15 lower. Standard AR-15 BCG compatibility simplifies maintenance and parts availability. Verify your lower receiver and magazine are compatible with .458 SOCOM before installation.
