🔗 Compatibility
Firearms: Barrels with 1/2×28 threaded muzzle
Calibers: Up to .223 Rem / 5.56 NATO (.368″ bore)
Not Recommended: Use with calibers larger than bore size (e.g., .30 cal, 9mm) without professional assessment
🔄 Suppressor Compatibility
The SARH 2 Port Muzzle Brake is designed to work seamlessly with the 13/16×16 ASR Adapter, enabling compatibility with SilencerCo’s ASR (Active Spring Retention) mounting system. This allows fast and secure attachment or removal of ASR-compatible suppressors, giving shooters greater flexibility in both suppressed and unsuppressed configurations.
🛠️ Installation Instructions
⚠️ Safety First: Always ensure the firearm is unloaded before installation.
Prepare the Barrel
Clean muzzle threads of carbon, oil, or debris.
Thread the Brake
Hand-thread the SARH brake until snug.
Align the Ports
Large side ports at 3 and 9 o’clock.
Secure the Brake
Tighten with a wrench an additional ¼ turn past hand-tight, or until properly timed.
Avoid overtightening to prevent thread damage.
Final Alignment Check
Use a bore rod or visual confirmation to ensure no obstruction is in the bullet path.
