EPES V2/V3 Cylinder Head MKII – 7075 Aluminium

The EPES V2/V3 Cylinder Head MKII is a precision internal upgrade designed for builders seeking improved compression, consistency, and gearbox longevity. Built from aerospace-grade 7075 T6 aluminium and finished with HET Teflon coating, this cylinder head delivers durability and performance in one component.

Key Features

• 7075 T6 aluminium construction – exceptional strength-to-weight ratio and corrosion resistance
• HET Teflon coating – reduces friction and wear for sustained performance
• Double O-ring sealing – minimises air loss and improves compression efficiency
• No Sorbo pad design – allows full customisation of compression system
• Adjustable grub screws – fine-tune gearbox play and preload for optimal sealing

Real-World Use Cases

This cylinder head suits builders upgrading V2 and V3 gearboxes for milsim events, skirmish tournaments, or dedicated target shooting rigs. The dual O-ring design is particularly valuable in builds where consistent velocity and air efficiency are priorities. Adjustable grub screws allow you to dial in compression after installing the cylinder, reducing the need for full gearbox reassembly during tuning.

Technical Specifications

• Compatibility: V2/V3 gearbox
• Material: 7075 T6 aluminium with HET Teflon coating
• Sealing: Double O-ring configuration

Compatibility & Upgrades

The EPES V2/V3 MKII is a drop-in replacement for standard cylinder heads in V2 and V3 gearboxes found in M4 platform rifles, M14s, and most AEG platforms. It pairs well with upgraded cylinders, nozzles, and high-performance motors to create tight, efficient compression chains.

UK Legal & Site Notes

As an internal gearbox component, this cylinder head is legal to own and use at all UK airsoft sites. It does not alter the external appearance or legal classification of your replica and may actually improve chronograph consistency at sites with velocity restrictions.
