TTI AIRSOFT Piston Head for AAP-01 / Marui G18C GBB

It works better than the cowcow piston head and the stock one and since the rubber part isnt as long as it was before it doesnt expand or overlap and tear so thats a plus most definetly its a cheap but highly recommended part

AAP-01C needs M3 20mm bolt

Works well with the factory bbh and nozzle, have good consistency and probably will last longer due to construction, than the factory piston head. It is NOT good for CCT lightweight bbh (or you need a longer screw than what it is supplied with)!

very good

Good price
