Rugged Suppressor OA010 3 Lug Adapter .45 ACP .578x28 Black

The Rugged Suppressor OA010 3 Lug Adapter is a dedicated .45 ACP suppressor attachment built around a .578"-28 tpi thread pattern and finished in a low-glare matte black. It screws onto any fixed-barrel host threaded in .578x28 and locks into Rugged's .45 ACP 3 Lug Mount, giving the shooter a fast, tool-free quick-detach interface between host and suppressor without the suppressor walk-off common to fixed-barrel pistol setups.

Designed to drop into the Obsidian45 ecosystem, the OA010 allows users of the Obsidian45 (and other Rugged-suppressor 3 Lug Mounts) to bring that same rapid 3-lug engagement to .45 ACP-threaded pistols, lever-action firearms, and other fixed-barrel hosts. The adapter integrates Rugged's patented Go/No Go Gauge, providing a visual confirmation that the suppressor is fully seated and locked before the firearm goes hot - a meaningful safety margin with the higher pressures and port-pop profile of .45 ACP pistol suppressors.

Installation is straightforward: thread the OA010 onto the host barrel's .578"-28 threads, torque to spec, and accept the male 3-lug interface of any Rugged .45 ACP 3 Lug Mount installed on a compatible suppressor. The matte black finish matches the Obsidian45 line and resists glare under weapon lights. Note that this is an adapter only; the suppressor and 3 Lug Mount are sold separately. For use on fixed-barrel firearms only.
