The Rugged Obsidian 9 is highly regarded for its modularity, allowing users to switch between a full-length (7.8 inches) and a short configuration (4.8 inches). In its full-length setup, it offers superior sound suppression, while the short mode provides a more compact option with slightly reduced noise reduction. Compared to other modular suppressors, the Obsidian 9 stands out for its durability, ease of disassembly, and excellent performance in both configurations.
