The SilencerCo ASR Flash Hider (brand part no. AC590) is the muzzle-side half of SilencerCo’s Active Spring Retention mounting system, cut to a 5/8×24 thread for .30 caliber and .308/7.62 NATO hosts. The ASR Mount is a quick attach and detach system compatible with almost all SilencerCo suppressors, letting a shooter go one-hand-on, one-hand-off between mounting and removing a can. Once shouldered, a locking ring keeps the suppressor from rotating or working loose during a heavy firing schedule. SilencerCo’s patent-pending resonance suppression design also eliminates the tuning-fork ring common to competing three-prong flash hiders.
