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 patentpending 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 such as Keymo and ASR. Every SG-556 suppressor is stamped with the Daniel name which means it’s backed with a 100% Satisfaction Guarantee. – FEATURES: – Cutting-edge gas-flow dynamics eliminate over-gassing and direct toxic gasses forward not back in a shooter’s face – Significantly reduces impulse noise levels protecting against hearing loss – Patent-pending gas-flow pathing stabilizes rounds for extreme accuracy and negligible point-of-impact shift – Patent-pending baffle stack and proprietary material coating reduces flash signature to virtually zero – Sturdy direct-thread attachment via included mounting adapter utilizing industry-standard HUB 1.375-24 UNS allows for secure mounting and attachment/detachment in seconds – Constructed of durable lightweight stainless steel tube and baffle stack – Made in the U.S.A. and features a 100% Satisfaction Guarantee – Weight: 22.0 oz (w/mount) – Length: 7 – Tube Diameter: 1.75 – Compatible Calibers: .223/5.56mm – Material Construction: Stainless Steel Baffle Stack – Stainless Steel Tube – Mounting: 1/2 x 28 TPI
