Rugged Suppressors OA009 3-Lug Adapter 45 ACP 9/16x24 Thread

The Rugged Suppressors OA009 3-Lug Adapter transforms any 45 ACP suppressor with 9/16"-24 threads into a quick-detach system. This precision-machined adapter eliminates the need to thread suppressors on and off repeatedly, reducing wear on barrel threads and suppressor baffles.

What Makes This Different

The OA009 features Rugged's proprietary 3-lug interface that locks with a simple quarter-turn twist, providing consistent lockup every time. Unlike traditional direct-thread systems that can work loose during firing, this adapter maintains zero shift through hundreds of mounting cycles. The hardened steel construction withstands the higher pressures and larger bore diameter of 45 ACP cartridges without compromising alignment.

Key Features

• Quick-detach 3-lug system for rapid suppressor mounting and removal
• Precision-machined from hardened steel with black nitride finish
• 9/16"-24 TPI threading compatible with most 45 ACP suppressors
• Self-timing design eliminates need for crush washers or shims
• Maintains consistent point of impact across mounting cycles
• Compatible with Rugged 3-lug muzzle devices and flash hiders
• Reduces barrel thread wear compared to direct-thread mounting

This adapter excels in tactical training environments where suppressors are frequently mounted and removed between different host weapons. The positive locking mechanism prevents accidental detachment during rapid fire sequences, while the repeatable lockup maintains accuracy standards required for precision shooting applications. The nitride coating resists corrosion from powder fouling and environmental exposure.
