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.

Key Features

  • M12x1.0 LH input matches CMMG PS90 SBR barrel
  • 1/2x28 RH output accepts standard 5.7x28 suppressors
  • Required only on CMMG-converted PS90 SBR builds

Pros

  • +Unlocks the entire 1/2x28 suppressor market on the CMMG SBR PS90
  • +Compact precision-machined adapter

Cons

  • −Only needed on CMMG SBR PS90 builds
  • −Adds a thread junction at the muzzle
  • −Only applies after the CMMG SBR barrel conversion
