Overview
The CMMG PS90 SBR conversion barrel uses an M12x1.0 left-hand metric muzzle thread, which is non-standard for the US suppressor market. This adapter from CMMG converts that proprietary thread to 1/2x28 right-hand so any 5.7x28-rated suppressor can mount direct-thread.
This adapter is needed only on PS90 builds using the 10.4-inch CMMG SBR barrel. The Dorin shroud is a different solution for the factory 16-inch barrel assembly and already exposes a 1/2x28 output. If you are running the CMMG SBR barrel specifically, this $70 adapter is the gateway to standard 1/2x28 suppressor mounts.
