Special Features
- The 3-port design redirects propellant gases upward and to the sides at the muzzle, countering muzzle rise and keeping the barrel on target between shots for faster and more accurate follow-up fire on both bolt-action and semi-automatic .30 caliber platforms
- The integrated ASR mount interface allows any compatible SilencerCo suppressor to thread directly over the muzzle brake using the ASR quick-detach system, converting a bare muzzle brake into a suppressor host in seconds with one hand and no tools
- The Active Spring Retention locking mechanism clicks audibly into place when a suppressor is mounted, providing positive confirmation that the suppressor is locked, centered, and secure before firing
- The black nitride finish provides superior surface hardness and corrosion resistance compared to standard blued or parkerized finishes, holding up to the heat, gas erosion, and environmental exposure that a muzzle device endures over extended shooting sessions
- Each AC591 ships with a shim set and Rocksett thread-locking compound, giving the installer everything needed for a properly timed, gas-sealed, and torqued installation right out of the package

- The 5/8x24 thread pitch covers the widest range of popular .30 caliber platforms including .308 Winchester, .30-06 Springfield, .300 Win Mag, .300 Blackout, and 7.62x39mm, making this a single solution for multi-caliber shooters
- The included shim set and Rocksett eliminate the need for a separate trip to the hardware store or gunsmith, making this a complete installation package for any shooter comfortable doing basic muzzle device work at home
- At 2.375 inches in length, the AC591 adds minimal overall length to the rifle, keeping the platform compact and well-balanced while delivering the full benefit of the 3-port brake design
