SilencerCo AC591 ASR Muzzle Brake 30 Cal 5/8x24 Black Steel

The SilencerCo AC591 ASR Muzzle Brake transforms standard rifles into suppressor-ready platforms while providing immediate recoil reduction benefits. This precision-machined brake features the patented ASR mounting system that enables rapid attachment of compatible SilencerCo suppressors. The aggressive port design redirects muzzle gases to significantly reduce felt recoil and muzzle rise during rapid fire sequences.

What Makes This Different

The ASR (Advanced Suppressor Ready) system sets this brake apart from traditional muzzle devices through its dual-purpose design. While standard brakes only reduce recoil, the AC591 serves as both an effective brake and a quick-detach suppressor mount. The precision-ground mounting surfaces ensure perfect alignment with ASR suppressors, eliminating point-of-impact shifts that plague many quick-attach systems. Independent testing shows 35-40% recoil reduction compared to bare muzzles.

Key Features

• Patented ASR quick-detach system for instant suppressor mounting
• Precision-machined 17-4 PH stainless steel with black Cerakote finish
• 5/8"-24 TPI threads compatible with most 30 caliber rifles
• Aggressive three-port design reduces recoil by 35-40%
• Self-timing design eliminates need for crush washers or shims
• Compatible with all SilencerCo ASR suppressors
• Wrench flats machined for easy installation and removal

Range performance demonstrates consistent accuracy maintenance across extended shooting sessions. The brake's gas redirection pattern minimizes dust signature in prone positions while maintaining effectiveness. Competition shooters report faster follow-up shot acquisition due to reduced muzzle movement. The robust construction handles high round counts from magnum cartridges without degradation. Weather testing confirms reliable function in extreme temperature and moisture conditions.
