Uncompromising piston head for perfect performance even with the strongest springs.
Dual O-ring design and 11 back pressure holes for maximum performance. Thanks to the use of aviation duralumin, this piston head can be used with even the strongest springs. The H+PTFE surface treatment then ensures a long service life and low friction.
- Duralumin piston head for the strongest springs, equipped with H+PTFE surface treatment
- The head is equipped with two high-quality O-rings (guide and sealing)
- 11 counter-pressure holes with sophisticated geometry for perfect tightness in the cylinder
- Ball bearing for trouble-free operation of the spring
- Weight of single head only 6g and 11.4g including bearing, flange and screw
- Made of aircraft aluminum alloy EN AW 7075 T6, O-rings made of NBR 70 sh
- Made in Czech Republic
- Package includes piston head with installed guide and sealing O-ring, guide and sealing O-ring of larger diameter (for cylinders with larger internal diameter, bearing with flange and strength bolts of several lengths

- 3 x strength screws of different lengths for possible use of AOE washers (M3×12 and M3×16 with torx head and M3×14 with cross head)
Sophisticated geometry of the back pressure system
The piston head is so-called counter-pressure, which is already an established standard today, but we still managed to move the proven design a little further.
EPeS piston head has 11 bearing holes for sealing O-ring. The placement of these holes has been chosen to maximize flat contact surfaces with the impact rubber of the head while maintaining excellent compression. The larger the functional area of the impact rubber, the more efficiently the shocks of the piston are absorbed, the weapon exhibits a quieter operation, and the life of the rubber is also extended.
The edges of the intake holes are rounded in the EPeS airsoft piston head to an ideal aerodynamic shape for effective air access to the sealing O-ring. But even more important is the disruption of the sharp transition between the straight face of the head and the hole. This sharp transition is in most cases the cause of damage to the impact rubber of the cylinder head.
