Gemtech
The Gemtech Piston GM9/MM9/Tundra 1/2-28 Thread Adapter for Suppressors is a field-swappable piston core designed to convert your TUNDRA or MULTIMOUNT LID suppressor to fit different host platforms. If you run multiple guns with different barrel threads, this adapter lets you keep one suppressor in the fight across your entire collection—just swap the piston in the field with no tools required. It's the kind of practical solution that makes sense for shooters who want flexibility without carrying multiple cans.
The real value here is simplicity and versatility. Suppressors are a significant investment, and this piston core extends that investment across your rifle lineup. The 1/2-28 thread is a common standard for smaller-caliber rifles and pistol-caliber platforms, making this a natural fit if you're running a GM9 or MM9 host or moving your TUNDRA between setups. Field installation means you're not tied to a workbench or gunsmith—change threads wherever you are.
This is the piston component only; the LID body, spring, and piston block are sold separately. Make sure your suppressor is a TUNDRA or MULTIMOUNT LID model before ordering—this adapter won't fit other Gemtech designs.
