The SilencerCo ASR Muzzle Brake 5/8×32, .46 Cal is an ASR muzzle brake from SilencerCo, built to 5/8×32 spec. SilencerCo machines it (SilencerCo part no. AC1557) to factory tolerances rather than as a generic aftermarket stand-in. It is a muzzle brake that vents propellant gas through its ports to cut felt recoil and muzzle rise, and it doubles as this suppressor’s mounting interface. Run bare, the brake tames recoil on its own for faster follow-up shots; with the suppressor threaded on, the same interface keeps the can indexed consistently. It is a practical pickup for a range bag or armorer’s bench that needs the correct part on hand before the next build.

Key Specifications

• 5/8×32 thread pattern is the thread this device mounts on, and it also sets the interface the suppressor itself indexes to.
• .46 caliber is the caliber this part is built and sized for.

Frequently Asked Questions

What thread does this muzzle brake require? It threads onto a 5/8×32 muzzle; confirm your barrel is cut to that pattern before ordering.

Does the brake still reduce recoil with the suppressor off? Yes, the ports vent gas and cut felt recoil whether or not the suppressor is threaded on; mounting the can adds sound and flash reduction on top of that.

What caliber is this part built for? It is sized for .46 caliber; running it on a different caliber host is not something the manufacturer specifies as safe or correct.
