The SilencerCo AC591 ASR muzzle brake is designed for .30 caliber and 7.62 mm firearms with a 5/8-24 thread pattern. Its three-port configuration helps reduce felt recoil and muzzle climb, supporting faster follow-up shots and improved control during range sessions, training, and field use. The brake is constructed from durable steel and finished in black for a practical, low-profile appearance.
The AC591 is compatible with all SilencerCo ASR mounts, providing quick one-hand-on, one-hand-off attachment and detachment when used with a compatible suppressor setup. This streamlined mounting system makes it easier to transition between suppressed and unsuppressed configurations without sacrificing a secure connection. The included shim set helps with proper installation and alignment, while Rocksett supports a reliable installation when applied according to the manufacturer’s instructions.
Built for shooters seeking improved firearm control and ASR system compatibility, the SilencerCo AC591 combines a compact three-port design with straightforward installation components. Verify your firearm’s caliber, barrel thread pattern, and ASR mount compatibility before purchase and installation. Professional installation is recommended when required, and all installation procedures should follow applicable firearm safety practices and SilencerCo guidance.
