Top Max - RedPower Piston Head in Derlin for Marui SRE

The shape of the front part of the piston head has been designed to further reduce the stress due to impact with the cylinder head PAD even at high ROF. The head has a small recess which reduces the contact surface with the inside of the cylinder, to reduce friction to a minimum. The ERGAL and DELRIN insert for fixing the piston head on the piston is designed to be able to use the TopMax piston head on any piston on the market.

The REDPOWER piston head for the Marui SRE platform, in the compression phase, uses the Venturi principle, thus generating a more homogeneous compression of the O-RING for any configuration in which it is installed. The compression chamber is sized to allow an optimal O-RING opening time in compression and to prevent more power than necessary from being delivered in FULL AUTO mode, creating surges in the trajectory of the pellets. The ERGAL and DELRIN insert for fixing the piston head on the piston, specific for the Marui SRE platform, is CNC made and has a revised design that allows the total weight of the Piston Head to be significantly lightened, with a consequent reduction in the striking mass which acts on the Cylinder Head.
