CLPD @A+Studio Novel Design Piston Head for Marui/1911/Hi-Capa/Standard Blow Back Housing

Are you having trouble with your Hi-capa or 1911 with the piston O-ring?

Does it not seal correctly?

Does the O-ring run out from the piston?

The CL Project Design Piston Head is a novel product for you!

It is not an O-ring anymore; the design is just like a tire, so gas goes into the piston will balance expand, perfectly sealing your nozzle.

No more headache with looking for the right size O-ring for your gun anymore!
