Gemtech’s GM-45/Blackside threaded end cap adapters enable you to mount your GM-45 or Blackside suppressor on fixed-barrel firearms. The adapter features a 5/8-24 thread pattern and matte black finish, providing a clean, integrated look while maintaining full compatibility with your suppressor system. Designed for .223 Remington and .300 AAC Blackout calibers, this accessory eliminates the need for a separate threaded barrel.
The threaded rear mount adapter provides a secure interface for using GM-45 and suppressor systems on fixed-barrel platforms. Note that GM-45 suppressors are rated for .300 Blackout with subsonic ammunition only. Installation is straightforward, and the matte black finish and direct compatibility reduce installation complexity while preserving the intended configuration for your suppressor. 300 Blackout build or expanding your versatile .223 platform, this adapter delivers a professional mounting solution.
