ATI MP409 9mm Muzzle Thread Adaptor 1/2x28 to 1/2x36 for MP409

The ATI GSG MP-40 9mm Muzzle Thread Adaptor - 1/2x28 is a precision-made ATI accessory designed to expand your MP409 platform's compatibility with common 1/2x36 suppressor mounting systems by converting the existing metric 13x1 threading to a standard 1/2x36 configuration. Crafted from high-quality metal and finished in a durable black coating, this adapter is carefully threaded to ensure concentric alignment for reliable performance and minimized point-of-aim shift, making it an excellent choice for shooters seeking a clean, hassle-free mounting solution. Specifically engineered for ATI GSG MP409 models, it provides a snug, secure fit that preserves accuracy and reduces chatter during rapid fire or precision follow-ups. While it broadens your suppressor mounting options, this adapter is not compatible with the .22 Long Rifle version, so matching the MP409 family is essential. Whether upgrading a range setup or enhancing field versatility, the ATI Thread Adapter offers a practical, dependable path to integrating compatible muzzle devices with your 9mm MP-40 platform, delivering consistent thread engagement, corrosion resistance, and streamlined maintenance for long-term field use.
