Daniel Defense SoundGuard SG-556 Direct Thread 1/2x28 Suppressor, Black The Daniel Defense SoundGuard SG-556 is a premium suppressor designed specifically for 5.56 NATO and .223 Remington platforms, engineered to deliver exceptional sound suppression, reduced muzzle flash, and nearly zero gas blowback. Unlike conventional suppressors that often increase over-gassing and blowback into the shooter's face, the SG-556 utilizes proprietary KGM technology with advanced gas-flow pathing to direct gasses forward. This not only ensures a cleaner, safer, and more comfortable shooting experience, but also maintains visibility and prevents distractions during rapid fire. Constructed from rugged stainless steel with a matte black finish, the SG-556 provides long-term durability while maintaining an ideal balance on the host firearm. The patent-pending baffle stack design stabilizes rounds for extreme accuracy and ensures negligible point-of-impact (POI) shift, allowing shooters to remain on target even under sustained use. Additionally, the internal coating and gas dynamics virtually eliminate visible muzzle flash, providing superior concealment in both tactical and low-light conditions. Measuring 7 inches long with a 1.75-inch diameter, the suppressor strikes an optimal balance between suppression efficiency and compact design. At 22 ounces, its weight distribution enhances firearm stability without being cumbersome. The SG-556 employs the industry-standard HUB 1.375-24 UNS mounting interface, combined with a 1/2x28 direct thread adapter, ensuring compatibility and versatility across multiple firearm platforms.
