Requires an ASR-mounted SilencerCo suppressor for quick-detach suppressor function.
The SilencerCo AC1561 ASR Flash Hider is a M13.5x1 LH threaded 9mm muzzle device for compatible metric left-hand threaded hosts. It works as a stand-alone flash hider and also serves as a suppressor mounting interface for compatible SilencerCo ASR suppressor setups.
SilencerCo designed the ASR Flash Hider to reduce visible muzzle flash while providing compatibility with the SilencerCo ASR Mount. When paired with the proper ASR-equipped suppressor, this muzzle device supports a quick attach/detach suppressor interface for compatible SilencerCo systems.
M13.5x1 LH Metric Thread Pattern: This AC1561 model uses M13.5x1 left-hand threads, a metric thread pattern commonly found on select European-style threaded 9mm barrels and host firearms. Always confirm the actual barrel thread pitch and thread direction before ordering.
ASR Suppressor Mount Compatibility: The AC1561 is part of SilencerCo’s ASR mounting family. It is intended for use with compatible SilencerCo suppressors and ASR mounts. Always confirm the suppressor model, ASR mount type, caliber rating, and barrel thread pitch before installation or suppressor use.
Flash Reduction with Resonance Suppression: SilencerCo states that the ASR Flash Hider significantly suppresses muzzle flash and uses a resonance suppression method intended to reduce the tuning-fork effect common with some 3-prong flash hider designs.
Installation Note: Proper installation is important for suppressor alignment. Use the correct shims, torque guidance, and installation method recommended by SilencerCo. Do not use a crush washer with suppressor-compatible muzzle devices.
Important Fitment Note: Always confirm barrel thread pitch, left-hand thread direction, caliber, bore clearance, suppressor compatibility, ASR mount compatibility, shoulder geometry, torque requirements, and alignment before installation or live fire.
