SilencerCo AC590 ASR Flash Hider 5/8x24 30 Cal/7.62mm Black Steel

The SilencerCo AC590 is a precision-machined steel flash hider built around SilencerCo's ASR (Active Spring Retention) quick-detach mounting system. Designed for 30 Cal / 7.62mm rifles, this black muzzle device allows fast, tool-free attachment and detachment of compatible SilencerCo suppressors - one hand on, one hand off - with a repeatable lockup from host to host.

Cut with 5/8x24 threading, the AC590 fits the standard muzzle spec on most modern .30-caliber rifles and serves as both a stand-alone flash suppressor and the secure mounting interface for ASR-compatible SilencerCo suppressors, including the Specwar line. The flash-hiding geometry tames muzzle signature in low-light shooting, while the integrated ASR collar delivers a solid, repeatable lockup under hard use.

Steel construction with a durable black finish gives the AC590 the heat tolerance and longevity expected of a duty-grade muzzle device, whether you are building out a precision .30-caliber rifle or a hard-use 7.62mm carbine.
