Rugged Suppressor OA004 Obsidian 3-Lug Adapter 9mm Luger 13.5x1 LH - Black

The Rugged Suppressor OA004 Obsidian 3-Lug Adapter is a dedicated mounting accessory for the Rugged Obsidian9 suppressor. This adapter replaces the standard piston assembly in your Obsidian9, allowing the suppressor to be mounted directly to 9mm Luger hosts equipped with a 3-lug interface - no separate piston or fixed barrel spacer required.

Built to 9mm HK specification, the OA004 is engineered specifically for 9mm Luger firearms and is not compatible with 45ACP Obsidian models. The adapter features a 13.5x1 LH thread pattern and is finished in a clean, low-reflective Black finish.

The OA004 incorporates Rugged Suppressor's patented Go/No Go Gauge, which provides clear visual confirmation that the suppressor is properly seated and locked to the host firearm before firing. This simple but effective feature takes the guesswork out of attachment, giving shooters confidence that the Obsidian9 is correctly mounted every time the suppressor goes on the gun.

Ideal for HK-pattern 9mm Luger pistols and PCCs fitted with a 3-lug barrel, the OA004 converts the Obsidian9 into a secure quick-detach 3-lug suppressor system.
