Forward Controls Design - 6315KM short for 9mm, Key Micro, 1/2x28 - 6315KM-S, 9mm, 1/2 x 28

The Forward Controls Design 6315KM-S 9mm is a compact muzzle device designed specifically for compatible 9mm firearms using 1/2x28 muzzle threads and the Dead Air Key Micro suppressor mounting system. At just 2.063 inches long, the KM-S provides a shorter alternative to the standard 6315KM while maintaining a suppressor-ready mounting interface for compatible Dead Air 9mm suppressors. The 6315KM-S uses the same general flash-suppressor concept as Forward Controls Design's 6315 family, but its shortened profile and larger 0.385-inch bore are optimized around 9mm use. FCD notes that while this 1/2x28 version can physically be installed on some .223/5.56 barrels, the larger bore and reduced length result in less flash suppression and muzzle-rise compensation than a dedicated 5.56 model. Its integrated Dead Air Key Micro interface allows the muzzle device to serve as both a compact flash suppressor and a mounting point for compatible 9mm suppressors. This makes the 6315KM-S a practical option for compact PCC and 9mm carbine configurations where overall muzzle-device length is an important consideration. For shooters building around the Dead Air Key Micro ecosystem, the Forward Controls Design 6315KM-S offers a compact 9mm-specific muzzle device with 1/2x28 compatibility and the rugged, purpose-driven design associated with the FCD 6315 family.
