Product Description

The Black Rain Ordnance 458 SOCOM complete upper delivers serious stopping power in a versatile, easy-to-install package. This 16″ upper allows you to convert an existing AR-15 lower receiver into a hard-hitting .458 SOCOM rifle without building from scratch. Simply pair it with any compatible lower and you have a complete firearm ready for duty or training.

The barrel is forged from 4150 chrome-moly vanadium steel and finished with a durable nitride coating for corrosion resistance. A purpose-built 458 SOCOM muzzle brake manages recoil while the billet charging handle with extended tactical latch ensures smooth, reliable operation under any conditions. The nitride-coated bolt carrier group rounds out a package built for longevity and performance.

Rail and Accessory Mounting

Additionally, the 15″ MLOK rail gives you modern attachment points for lights, lasers, grips, and optics. This rail platform supports today’s tactical accessories without the bulk of older designs.
