SilencerCo's 3-prong flash hider is compatible with the ASR mounting system. It features a one hand on, one hand off attachment/detachment and patent-pending resonance suppression which effectively eliminates the tuning-fork effect common with competing 3-prong flash hiders. The 3-port muzzle brake design effectively reduces felt recoil and muzzle climb.
