Forward Controls Design - 6315KM short for 9mm, Key Micro, 1/2x36 - 6315KM-S, 9mm, 1/2 x 36

The Forward Controls Design 6315KM-S 9mm is a compact muzzle device designed for compatible 9mm firearms with 1/2x36 muzzle threads. Built around the shorter 6315KM-S profile, it combines flash suppression and muzzle-rise control with a Dead Air Key Micro-compatible suppressor mounting interface. At approximately 2.063 inches long, the 6315KM-S is notably shorter than the standard 6315KM. Its asymmetric port layout uses smaller 3 and 9 o'clock ports and larger upward-facing ports to direct more gas upward, helping control muzzle movement without creating the excessive concussion associated with many dedicated muzzle brakes. This 9mm-specific version uses a 0.385-inch bore and is compatible with Dead Air Key Micro 9mm suppressor systems. The 1/2x36 configuration weighs approximately 3.55 ounces, making it a compact suppressor-ready option for compatible pistol-caliber carbines and 9mm rifle platforms. Designed and made in Texas, USA, the FCD 6315KM-S provides a purpose-built combination of compact dimensions, 9mm compatibility, muzzle control, and Key Micro suppressor mounting capability.
