Radical Defense KFM Flash Hider Features The Radical Defense KFM Flash Hider is engineered to disperse and cool propellant gases as they leave the muzzle cutting down the visible flash signature that can affect a shooter s vision in low-light conditions. Built for .30 caliber rifles it threads onto a 14x1M left-hand pattern matching the muzzle thread found on specific .30 caliber platforms using that standard. The device s geometry is shaped to direct gas forward and outward rather than back toward the shooter helping preserve a clear sight picture shot to shot. Its compact profile keeps the muzzle device from adding excessive length or weight to the front of the barrel. Finished in a durable black coating the KFM Flash Hider is built to withstand repeated firing cycles and the heat generated at the muzzle without degrading. Precision machining ensures the device threads on cleanly and indexes properly on guns cut with a matching left-hand thread. Radical Defense builds its muzzle devices for shooters who want dependable flash reduction without resorting to a bulky brake or compensator. This flash hider is a simple effective option for anyone running a .30 caliber rifle who wants better control of muzzle signature.
