Forward Controls Design 6310KM, Long (2.7"), 5/8x24 - 6310KM-L

The Forward Controls Design 6310KM-L is a long-format flash suppressor and compensator designed for compatible .30-caliber rifles with 5/8x24 muzzle threads. Measuring 2.7 inches long, the extended profile makes it well suited for select barrel-length and pin-and-weld configurations while retaining the performance characteristics of FCD's 6310 design. Its asymmetric port geometry helps reduce muzzle rise while maintaining effective flash suppression without the increased concussion associated with a dedicated muzzle brake. The integrated Dead Air KeyMo mounting interface allows the 6310KM-L to serve as a suppressor mount for compatible KeyMo-equipped suppressors and adapters. Built for shooters who want flash reduction, improved muzzle control, and suppressor compatibility, the 6310KM-L combines an extended profile with FCD's purpose-driven muzzle device design.
