The Rugged Suppressors Obsidian9 3 Lug Adapter is designed for 9mm HK-spec barrels with 1/2×28 threading. It is compatible with the Rugged Obsidian9 3 Lug Mount and includes a Go/No Go Gauge to help verify proper attachment. This adapter is not compatible with .45 ACP.
Rugged Suppressors recommends using Red Loctite and applying 20–25 ft-lbs of torque when installing the adapter on a barrel. The integrated Go/No Go Gauge adds a practical installation check for users configuring an Obsidian9-compatible 3 lug setup.
With its defined 1/2×28 thread pattern, 9mm HK-spec design, and compatibility with the Obsidian9 3 Lug Mount, this adapter provides a purpose-built solution for an appropriate suppressor mounting configuration.
