The Obsidian9 sets a new standard for 9mm suppression, optimized for maximum sound reduction while remaining light and compact. The innovative ADAPT Module provides two suppressors in one, allowing you to choose between maximum suppression and a shorter, lighter configuration. With a 1.37" diameter, the Obsidian9 is compatible with pistol suppressor sights, making it perfect for pistols or subguns. In a class of its own, the Obsidian9 shrinks to nearly half its size in the short configuration, giving you two suppressors with a single tax stamp. Its compatibility with suppressor sights adds even more versatility, ensuring seamless use on pistols or carbines. The Obsidian9's baffles are machined from 17-4 stainless steel barstock and feature three indexing tabs for precise alignment. The baffles create a gas seal that virtually eliminates carbon buildup between the baffles and tube, making serviceability a breeze. The non-slotted design creates a full circumference gas seal, drastically reducing gas blowback for a more enjoyable shooting experience. The Obsidian9 mount, machined from 17-4 stainless steel barstock, features strategically placed engraving on the thickest cross section for easy replacement if damaged, and allows for future upgrades.Obsidian45 pistons, fixed mounts, fixed barrel spacers, and 3-lug mounts are all interchangeable with the Obsidian9. Built from premium materials to last a lifetime and withstand any rate of fire, the Obsidian9 is ready for anything you throw at it.
