Rugged Suppressors OA008 3-Lug Adapter 45 ACP 5/8x24 Thread

The Rugged Suppressors OA008 3-Lug Adapter transforms any 5/8"-24 threaded suppressor into a quick-detach system for 45 ACP firearms. This precision-machined adapter eliminates the need to thread and unthread suppressors repeatedly, reducing wear on threads while enabling rapid mounting and removal.

What Makes This Different

Unlike standard direct-thread mounting systems, the OA008 utilizes a proven 3-lug interface that locks securely with a simple quarter-turn. The adapter maintains perfect concentricity through CNC-machined tolerances that exceed industry standards. Steel construction withstands the higher pressures and larger bore requirements of 45 ACP cartridges while maintaining structural integrity through thousands of rounds.

Key Features

• Quick-detach 3-lug system enables rapid suppressor mounting in seconds
• Precision CNC-machined from hardened steel for maximum durability
• 5/8"-24 TPI threading fits standard 45 ACP suppressor mounts
• Maintains perfect bore alignment to prevent baffle strikes

The adapter performs consistently across various 45 ACP platforms, from compact pistols to carbines. Law enforcement and competitive shooters rely on the 3-lug system for rapid transitions between suppressed and unsuppressed configurations. The steel construction handles full-auto fire and high round counts without loosening or degrading accuracy.
