Daniel Defense Soundguard SG-556 w/ SilencerCo QD Bravo ASR Adapter, 5.56mm, Suppressor

Daniel Defense SoundGuard SG-556 with SilencerCo Bravo ASR Mount

The Daniel Defense SoundGuard SG-556 is a stainless steel suppressor for .223 Remington and 5.56mm firearms, paired here with a SilencerCo Bravo ASR quick-detach mount. This specialized package combines SoundGuard gas management with an established mounting interface for compatible ASR-equipped rifles. The included adapter is the Bravo-size ASR mount, part number AC824.

For a shooter building a dedicated 5.56 suppressor setup, the important combination is the SG-556's caliber rating, its HUB rear interface and the supplied Bravo ASR adapter. A compatible ASR muzzle device is required on the host firearm.

Stainless Steel Construction and Forward Gas Management

The SG-556 uses stainless steel for both the tube and baffle stack, with a 1.75-inch tube diameter. Its gas-flow design directs combustion gases forward to help reduce blowback toward the shooter. That makes gas management a central feature of the suppressor, alongside reducing the firearm's impulse noise.

The SoundGuard baffle design and coating on internal components also address muzzle flash. These features work together as a system for controlling the gas, sound and flash produced during firing. The durable steel construction suits a dedicated rifle suppressor that will see regular range use.

Included SilencerCo Bravo ASR Quick-Detach Mount

ASR stands for Active Spring Retention. The SilencerCo Bravo ASR mount connects the suppressor to a compatible ASR muzzle device and uses a locking ring to resist rotation during use. The quick-detach format is useful when moving the suppressor among properly configured, compatible firearms or removing it for storage.

The ASR system supports designated SilencerCo ASR flash hiders and muzzle brakes. The Bravo adapter is the suppressor-side component of that connection. Match the host muzzle device to the firearm's caliber and muzzle threads, as well as the ASR interface.

HUB Interface and Caliber Compatibility

The SG-556's rear mounting interface follows the HUB 1.375-24 UNS standard. HUB identifies the suppressor's adapter connection; the muzzle device supplies the connection to the barrel. These are separate interfaces, and both must match the intended setup.

This suppressor is specified for .223 Remington and 5.56mm. The adapter's ability to fit another firearm does not expand that caliber rating. Confirm the complete host, muzzle-device and suppressor combination before purchase.
