Enhance the performance and versatility of your FN PS90 SBR build with the CMMG Thread Adapter. Designed specifically for the 10.4" short barrel, this precision-machined adapter offers a dual-purpose solution: it serves both as a barrel retention device and a 1/2" x 28 thread adapter for your favorite muzzle devices.
Whether you're adding a suppressor, flash hider, or compensator, this adapter is built to meet the demands of serious PS90 enthusiasts seeking high-quality components for custom configurations.
Key Features:
- 2-in-1 Functionality: Combines a 1/2" x 28 muzzle thread adapter with secure barrel retention.
- Threaded for Compatibility: Attaches directly to the M12 x 1.0 left-hand threads found on CMMG’s 10.4" PS90 barrel.
- Durable Build: Constructed from high-strength materials for long-term performance.
- Accessory-Ready: Easily mount suppressors, flash hiders, or compensators to expand your build’s capabilities.
Installation Note:
Installation may require specialized tools and knowledge. Professional installation is highly recommended.
Important Operating Note:
Once installed, the barrel will have a small amount of rotational and front-to-back movement. This is normal and required for the PS90's proper delayed-blowback operation.
Pro Tip:
Before attaching any muzzle accessory, clean the adapter’s threads with solvent and a copper wire brush. This ensures a clean fit and avoids overtightening or damage from leftover manufacturing debris.
