Product Description

Daniel SoundGuard is powered by cutting-edge gas-flow dynamics that eliminate over-gassing and direct most gases forward, not back into a shooter's face. You experience less toxic gas blowback and can focus on putting more shots on target. State-of-the-art technology significantly reduces impulse noise levels, helping protect against hearing loss, while a patent-pending baffle stack and proprietary coating on internal parts reduce a firearm's flash signature to virtually zero. Patent-pending gas-flow pathing stabilizes rounds, ensuring extreme accuracy with minimal point-of-impact shift.

Features
  • Rated for .223 Remington and 5.56 NATO
  • HUB Compatible
