The Obsidian9TM is optimized for 9mm for additional suppression while staying light and compact. Our ADAPT Module gives you 2 lengths in one suppressor for maximum suppression or weight/ length savings. With a diameter of 1.37 the Obsidian9 is compatible with pistol suppressor sights making it perfect for pistols or sub-guns. – ADAPT Modular Technology – Now you don’t have to choose between a short rifle suppressor and a long one. With ADAPT Modules you get two lengths with one tax stamp. So you can have a shorter and lighter suppressor in seconds compared to months. – 17-4 Stainless Steel Baffles – Obsidian9 baffles are machined from 17-4 Stainless Steel barstock. This allows for more cleaning options and increases durability. Our baffles also create a gas seal to prevent carbon build up between the baffles and tube for ease of maintenance. – Strategically Placed Engraving – We strategically place the serialized engraving over – the thickest Stainless Steel cross section of the suppressor. This allows fast and easy repairs should the suppressor become damaged beyond repair. – Non-slotted Piston – The Obsidian9/45 uses a non-slotted design creating a full circumference gas seal. This drastically lowers gas blowback for a more enjoyable shooting experience. Obsidian9/45 pistons are cross compatible with SilencerCo slotted pistons. – SPECIFICATIONS – CALIBER: – Rated for Pistol Calibers up-to 9mm 300BLK – Subsonic and 350 Legend – DIAMETER: 1.37 – LENGTH: – Standard Configuration: 7.8 – Short Configuration: 4.85 – WEIGHT: – Standard Configuration: 12.7oz – Short Configuration: 8.7oz – MATERIALS – Baffles & Mount: 17-4 Stainless Steel Tube: – Hard Coat Anodized Aluminum Finish: High Temp Cerakote® – FEATURES – ADAPT Modular Technology – User Serviceable – Revolutionary Mounting System – Non-Slotted Piston Design Interchangeable – End Caps – 17-4 Stainless Steel Indexed Baffles – Belt Fed Rated® – INCLUDES – 1/2×28 Piston – 9mm Front Cap – Obsidian9TM Suppressor – ADAPT TM Module – Operator’s Manual – Rugged Suppressors Sticker – Obsidian9 Sticker – ACCESSORIES MOUNTS: – Pistons (multiple thread pitches available) – 3 Lug Mount – Fixed Barrel Spacer – Fixed Mount – ACCESSORIES: – 9mm Front Cap – O-Ring Pack – Obsidian Spring Retainer / 3 Lug Tool – 3 Lug Adapter
