The SilencerCo ASR Flash Hider greatly reduces muzzle flash, protecting the shooter’s vision, especially in low-light conditions. Designed for maximum performance, this flash hider keeps your shots hidden and accurate. Improve your shooting with less flash signature and better control. Additionally, the SilencerCo Flash Hider features a patent-pending resonance suppression system that effectively eliminates the tuning-fork effect common with competing 3-prong Flash Hiders.
