AAP-01 / TM G18C Piston Head Red – TTI Airsoft

TTI Airsoft piston head for the Action Army AAP-01 and Tokyo Marui G18C GBB pistols. Made of aluminium, it replaces the original head of the blowback unit and is an upgrade part that keeps the slide cycling efficiently.

Operation

The piston head seals the blowback chamber: the gas entering it with every shot pushes against the head and drives the slide back. When the original head is worn, gas leaks past it, recoil loses strength and cycling becomes irregular; a new head restores the seal and a crisp blowback.

Mounting

It is fitted with the slide removed, in place of the original head, and secured to the cylinder unit with the central screw. On some versions, such as the AAP-01C, and with some aftermarket cylinder units the supplied screw may be too short: in that case an M3 x 20 mm screw is needed.
