Rugged Suppressor OA005 3 Lug Adapter 9mm 1/2x36 Black

The Rugged Suppressor OA005 3 Lug Adapter is a quick-detach mount accessory engineered for 9mm Luger host firearms threaded in 1/2"-36 tpi. Machined to 9mm HK specification, the adapter threads directly onto the barrel and serves as the male mating component for any compatible 3-lug suppressor mounting system, letting the shooter attach or remove their suppressor in seconds without tools.

A key feature is the patented Go/No Go Gauge built into the adapter, which provides clear visual and tactile confirmation that the suppressor is fully and correctly seated before firing. This built-in gauge takes the guesswork out of suppressor attachment and helps ensure a secure, surprise-free lockup at the range. The unit is finished in a low-glare black coating to blend with most host firearms and suppressor finishes.

The OA005 is designed for use with the Rugged Obsidian9 and Obsidian45 suppressors and any other 3-lug compatible mount built to 9mm HK dimensions. This adapter is NOT compatible with .45 ACP 3-lug mounts - operators should verify their host barrel threads and intended suppressor before installation.
