The polycarbonate piston head have built-in pressure bearings to reduce friction from the spring. The piston head are ventilated making sure that the rubber seals are pressed against the cylinder sides when the air is compressed.
The FPS ERGAL piston head is a great upgrade that will increase the efficiency of airflow through the cylinder. This piston head has ports on the front to push out the o-ring as it moves forwards, this ensures that all of the air in the cylinder is being pushed out to propel the BB.100% MARUI COMPATIBLE100% MADE IN ITALY
