FPS CNC ERGAL Double O-Ring Ball Bearing AEG Piston Head Pressure Deviation (XPAE).
XPAE new version with X-RING and one piece plastic shim for AOE.
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.
The ball bearings help reduce tension created by the spring compressing and
expanding, this combined with a ball bearing spring guide is the optimal set up to
keep your spring in good shape.
Each FPS piston head is made of ergal and it is also anodized for smooth surface finish.
This is the most advanced version with 6 ventilation holes.
Designed to divert the pressure in the inner part of the oring increasing dilation,
double o-ring and ball-bearing.
The piston head is constructed out of CNC ERGAL for durability and precision.
