SilencerCo AC141 ASR Flash Hider 5.56x45mm NATO 1/2x28 Black Steel

The SilencerCo AC141 ASR Flash Hider is a 3-prong muzzle device engineered for 5.56x45mm NATO and .223 Remington rifles. Cut from durable steel with a black finish, this flash hider tames muzzle flash during rapid strings of fire while serving as the dedicated mounting point for SilencerCo's ASR (Active Spring Retention) quick-detach suppressor interface.

The AC141 installs on any barrel threaded 1/2"-28 tpi, the standard pitch on most 5.56/.223 AR-pattern rifles. When suppressor use is on the menu, the AC141 mates directly to SilencerCo's ASR series mounts, including the Specwar 5.56, Specwar 7.62, Harvester Big Bore, and Omega ASR mounting systems, locking the can on or off in seconds without tools.

Whether you run the AC141 as a stand-alone flash hider or as the foundation of a quick-detach suppressor rig, it delivers the precision fit and repeatable lock-up the ASR system is built around.
