T-3D Printed Piston Head for Hi Capa

Description

3D printed piston head for Hi-Capa gas blowback pistols. Designed by Tangalala from GSAU Discord server.

A budget aftermarket part to ensure a good seal between the nozzle and pistol head to reduce possible leaks during cycling to improve gas efficiency. Designed for imported Hi-Capa Nozzles (Guarder, Cowcow, etc.)

3 o-rings are provided:

• Red 13mm – For nozzles with very small ID, uncommon to see
• White 13.5mm – For standard seal/fitment for most nozzles, Guarder, Cowcow, AA.
• Green 14mm – For very good seal between nozzle and bbu, a sufficiently strong nozzle spring is recommended to be paired with this as it introduces more resistance to the nozzle travel.

*Will not suit AW/WE Hi-Capa as those require a 15mm piston head. Have not tested with DB and GE Hi-capas.
