Gemtech Piston for GM-9, Multimount 9 or Tundra LID 1/2x36mm MFG # PISTON-GM9 UPC # 609728889357
An extra LID Piston Core allows you to easily change threads on a TUNDRA or MultiMount LID to use one suppressor on U.S. standard threaded pistols (1/2x28), European threaded pistols (M13.5x1mm LH), or even 9mm AR15 carbines (1/2x36-requires piston blocking tube). Installs in the field without the use of tools.
