Gemtech Piston for GM-9/Multimount-9 or Tundra LID MFG # PISTON-GM9 UPC # 609728889340
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 (1/2-28), European threaded pistols (M13.5x1mm LH), or even 9mm AR-15 carbines (1/2-36 - requires piston blocking tube). Installs in the field without the use of tools.
