The Daniel Defense SoundGuard SG-556 is compatible with .223 and 5.56mm caliber firearms and uses lightweight, durable stainless steel. It attaches/detaches in seconds via an included adapter utilizing an industry-standard HUB. Every SG-556 suppressor is stamped with the Daniel name, which means it’s backed with a 100% Satisfaction Guarantee from the manufacturer.
The SoundGuard series uses KGM Suppressors’ cutting-edge gas-flow dynamics that eliminate over-gassing and direct most gasses forward, not back in a shooter’s face. You experience less gas blowback and can focus on putting more shots on target. State-of-the-art KGM technology significantly lowers impulse noise levels, protecting against hearing loss, while a patent-pending baffle stack and proprietary coating on internal parts reduce your firearm’s flash signature to virtually zero. Patent-pending gas-flow pathing stabilizes rounds to ensure extreme accuracy with minimal point-of-impact shift.
