CMMG 57DA53A Thread Adapter 5.56/.223 1/2-28 TPI PS90 Steel

The CMMG 57DA53A Thread Adapter transforms the FN PS90's proprietary barrel threading to standard 1/2"-28 TPI, enabling compatibility with a wide range of muzzle devices and suppressors. This precision-machined adapter eliminates the need for specialized PS90-specific accessories while maintaining the platform's reliability and accuracy.

What Makes This Different

Unlike generic adapters that compromise fit and function, the CMMG 57DA53A features precision CNC machining from high-grade steel with exact dimensional tolerances. The adapter maintains perfect bore alignment through its stepped internal design, preventing baffle strikes and accuracy degradation. Heat-treated construction withstands the thermal cycling of rapid fire while the black oxide finish resists corrosion in all environments.

Key Features

• Converts proprietary PS90 threading to standard 1/2"-28 TPI for universal muzzle device compatibility
• CNC-machined from high-grade steel with black oxide finish for maximum durability
• Precision bore alignment prevents suppressor strikes and maintains accuracy
• Heat-treated construction handles sustained firing without degradation
• Compact profile adds minimal length to overall barrel configuration
• Compatible with all standard 5.56/.223 muzzle devices and suppressors
