Rugged Suppressor Obsidian 9 Fde

The Rugged Suppressor Obsidian 9 FDE is a modular 9mm suppressor built for shooters who want flexibility without compromise. Whether you're running a compact pistol, a suppressed PCC, or testing subsonic loads, the Obsidian 9 delivers effective sound reduction in two configurations—standard length for maximum suppression or short config for nimble handling—all under a single tax stamp. The 1.37-inch diameter keeps it slim enough to coexist with pistol suppressor sights, and the FDE finish blends seamlessly with modern duty and hunting setups.

At its core, the Obsidian 9 is engineered for practical shooter life. The 17-4 stainless steel baffles are machined from solid bar stock, rated for 9mm, 300 BLK subsonic, and 350 Legend, and they create an internal gas seal that keeps carbon buildup between the baffles and tube to a minimum. That means less disassembly hassle and easier cleaning. The non-slotted piston design seals against the entire circumference, dramatically reducing gas blowback—a real quality-of-life upgrade for high-round-count range sessions. Rugged's indexed baffle design also lets you swap end caps without losing zero, so you can tune suppressor length to mission and reload times in seconds.

The Obsidian 9 ships with a 1/2x28 piston, 9mm front cap, and Rugged's proprietary ADAPT module. If you need different mounting threads or add-on configurations, Rugged offers a range of pistons, 3-lug mounts, and fixed mounts. The serialization is placed strategically over the thickest steel cross-section, ensuring fast repairs if things go wrong. Built tough, serviceable by you, and designed for real-world use—this is a suppressor that earns its place in your safe.
