Rugged Suppressors Obsidian9 3-Lug Mount

The Rugged Suppressors Obsidian9 3-Lug Mount (brand part no. OA001) is a 9mm quick-attach mount built for the Obsidian9 suppressor, using the widely adopted 3-lug interface found on SOCOM-pattern pistols and PCCs. It replaces the factory barrel with one that carries the 3-lug nub pattern, letting the suppressor lock on and off in seconds without threading or torque specs to track. Because 3-lug is a common military and commercial standard, the same mount works across a range of compatible 9mm hosts. It is sold as mounting hardware only, separate from the suppressor tube itself.

Key Specifications

• Chambered for 9mm, it matches the pressure and bore of standard 9mm pistol and carbine hosts.
• The 3-lug mounting pattern gives a quick-detach interface that doesn’t require re-zeroing torque on every installation.
• An overall length of 1.5 inches keeps the mount compact on shorter pistol-caliber barrels.
• Built as the dedicated mount for the Obsidian9 suppressor platform, ensuring a purpose-matched fit rather than a generic adapter.
