Daniel SoundGuard Powered by KGM Suppressors utilize cutting-edge gas-flow dynamics that eliminate over-gassing and direct most gasses forward not back in a shooter s face. So you experience less toxic gas blowback and can concentrate 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 a firearm s flash signature to virtually zero. Patent-pending gas-flow pathing stabilizes rounds to ensure extreme accuracy with minimal point-of-impact shift. The SG-556 is compatible with .223 and 5.56mm caliber firearms and is constructed of lightweight but extremely durable stainless steel so you don t have to baby it and it won t weigh down your barrel. It attaches/detaches in seconds via an included adapter utilizing the HUB standard 1.375-24 UNS which provides secure attachment while adding minimal length and allowing for the use of a variety of other muzzle attachments. Every SG-556 suppressor is stamped with the Daniel name which means it s backed with a 100% Satisfaction Guarantee. TECHNICAL SPECIFICATIONS: Weight: 22 oz Length: 7 Diameter: 1.75 Materials: Stainless Steel Baffle Stack and Tube Finish: Black High-Temp Cerakote Thread Pitch: 1/2x28 Full Auto Rated!
