The SG-30TiL is compatible with .223 through .300 PRC caliber firearms and features an adjustable-port endcap for maximum recoil reduction regardless of a firearm's caliber or configuration. It is constructed of extremely lightweight and durable titanium. It attaches/detaches in seconds via an included titanium adapter utilizing an industry-standard HUB that allows for the use of a variety of other muzzle attachments, such as Keymo and ASR. Every SG-30TiL 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. All silencers require the purchase of a $200 Federal Tax Stamp.
