The silencer-optimized Radian R0006 RAPTOR SD Charging Handle Ambidextrous Design features a ported shaft designed to redirect gasses down and forward, away from the shooter's face when shooting suppressed. Its ambidextrous design allows rapid palm blading or finger-thumb charging of the weapon, ensuring the motion is fluid and fast from either strong or support side.
