Guarder Bore-Up Polycarbonate Piston Head

The Guarder Bore-Up Polycarbonate Piston Head is specifically designed for use in a Bore-Up Cylinders with Systema and/or Guarder specifications.

A Bore-Up set uses a larger air volume and is usually used in combination with a wide bore barrel (6.05mm and above). You can also use this set if, for example, you want to use a longer barrel than is standard in your airsoft replica.

Please note, standard parts can never be used in combination with this Piston Head, for example. This is due to different dimensions.
