SilencerCo AC142 ASR Muzzle Brake 5.56 NATO 1/2x28 Black Steel

The SilencerCo AC142 ASR Muzzle Brake transforms standard AR-15 platforms into suppressor-ready systems while delivering exceptional recoil reduction. This precision-machined brake serves dual purposes as both a standalone muzzle device and quick-attach mount for SilencerCo ASR suppressors. Built from heat-treated steel with a durable black finish, it handles high round counts without performance degradation.

What Makes This Different

Unlike traditional muzzle brakes that only reduce recoil, the AC142 integrates SilencerCo's proven ASR mounting system for instant suppressor attachment. The brake reduces felt recoil by approximately 40% compared to standard flash hiders while maintaining zero shift when transitioning between suppressed and unsuppressed configurations. This dual-function design eliminates the need for separate muzzle devices and suppressor mounts.

Key Features

• ASR quick-attach compatibility with all SilencerCo ASR suppressors
• Precision 1/2"-28 TPI threading for 5.56x45mm NATO/.223 Remington
• Heat-treated steel construction with corrosion-resistant black finish
• Three-port design reduces recoil and muzzle climb effectively
• Maintains consistent point of impact when adding or removing suppressors
• Compatible with standard AR-15 and similar 5.56 NATO platforms
• Wrench flats machined for secure installation with standard tools

Field testing demonstrates consistent performance across various ammunition weights and powder charges. The brake's port configuration directs gases laterally and rearward, significantly reducing muzzle rise during rapid fire sequences. Competition shooters report faster target reacquisition times, while tactical users benefit from improved control during sustained fire. The steel construction withstands temperature extremes and maintains timing through thousands of rounds.
