SILENCERCO AC1570 ASR FLASH HIDER 1/2X28 9MM

The SilencerCo ASR Flash Hider (AC1570) is a 9mm, 1/2x28-threaded 3-prong flash hider built to function as both a standalone muzzle device and a dedicated host attachment point for SilencerCo's Active Spring Retention suppressor mounting system. Whether you run it as a flash hider on a 9mm pistol-caliber carbine or as a suppressor-ready muzzle device, this 9mm ASR flash hider for PCC and pistol-caliber platforms delivers dual-purpose performance in one compact unit.

Special Features

• SilencerCo engineered a patent-pending resonance suppression method into the 3-prong design, eliminating the tuning-fork vibration effect that plagues most competing flash hiders at this price point.
• The ASR interface allows one-hand attachment and one-hand detachment of a compatible suppressor, putting the transition from unsuppressed to suppressed fire within reach of a single motion.
• The black nitride finish bonds to the steel at the surface level, giving the device hardness and corrosion resistance without adding coating thickness that could affect the ASR interface fit.
• The closed-tine prong geometry controls muzzle flash without the structural fragility common to open-tine 3-prong designs, keeping the device intact under sustained fire.
• At 2.46 inches, this flash hider provides enough length to satisfy legal barrel length requirements when pinned and welded to a 14.5-inch barrel.

Practical Benefits

• The AC1570 fits any 9mm platform threaded 1/2x28, including AR-pattern pistol-caliber carbines, dedicated 9mm AR builds, and pistols with threaded barrels, making it one of the most broadly compatible 9mm muzzle devices in the SilencerCo lineup.
• Running suppressed on a PCC becomes straightforward with this device installed, because the ASR mount threads directly over the flash hider without requiring a separate adapter or muzzle device swap.
• Flash reduction from the 3-prong design protects your night vision and low-light target acquisition during home defense drills and low-light range training without any adjustment after installation.
• Competitive and recreational 9mm carbine shooters benefit from the clean muzzle signature and the fast suppressor transition the ASR system provides between stages or strings of fire.
• If you are building or upgrading a 9mm PCC and want a muzzle device that pulls double duty as a flash hider and suppressor host, your AC1570 eliminates the need to buy two separate devices for two separate roles.

The SilencerCo ASR Flash Hider (AC1570) in 9mm with 1/2x28 threading is a capable tool and a solid fit for any 9mm carbine or pistol shooter who wants proven flash suppression and a direct path to running a SilencerCo suppressor.
