One Horse 7.5" .300 BLK SOCOM Pistol 1:7 M-LOK Complete Upper - OH-CU06

One Horse 7.5″ .300 BLK SOCOM Pistol 1:7 M-LOK Complete Upper

The One Horse 7.5″ .300 BLK SOCOM Pistol 1:7 M-LOK Complete Upper is built for shooters who want a compact, maneuverable upper for close-range work, defensive setups, and specialized AR-15 pistol builds. Its 7.5-inch .300 Blackout barrel uses a 1:7 twist rate to help stabilize a wide range of bullet weights, making it a strong fit for both subsonic and supersonic ammunition. One Horse positions this upper as a close-quarters option that is especially well-suited for tactical and suppressed applications.

The upper includes a 7-inch M-Lok handguard that keeps the profile compact while still giving the user room to mount accessories where needed. A nitride-finished bolt carrier group is included for smoother cycling, improved surface durability, and easier maintenance, and the package also includes a standard charging handle, so the upper is ready to pair with a compatible lower receiver. The product page states that it is built to Mil-Spec standards and designed to mount on any AR-15 Mil-Spec lower receiver.
