SilencerCo ASR Flash Hider .223/5.56 1/2-28

The SilencerCo ASR Flash Hider is a 3-prong muzzle device made to interface with SilencerCo’s ASR (Active Spring Retention) quick-attach mounting system. It enables one-hand-on, one-hand-off installation and removal of compatible ASR suppressors and uses a locking ring to help keep the suppressor secure under heavy use. The flash hider incorporates a patent-pending resonance suppression design that mitigates the tuning-fork effect often seen in competing 3-prong devices. It is intended for use on firearms chambered in .223 Rem / 5.56 NATO where the 1/2-28 thread pattern is required.
