EPeS Airsoft Gearbox Cylinder Head Mk.II V2/3

EPeS Airsoft Gearbox Cylinder Head Mk.II V2/3

A revolutionary cylinder head for V2 and V3 gearboxes. Our unique design solution brings a new standard of quality and performance.
Affixing the cylinder head inside the gearbox prevents undesired movements during fire.

The innovative design allows for a longer stroke of the tappet plate for maximum performance and reliability of your AEG.
The combination of uncompromising manufacturing quality, which ensures perfectly smooth surfaces, and unique H+PTFE surface finish allows for a maximally fluent operation of the nozzle.

The material used for the construction – aircraft-grade duralumin with H+PTFE surface finish – ensures longevity of parts.

Special impact rubber pads of our own design are made from durable polyurethane to improve airflow and provide maximum longevity and impact absorption.

They are available in three stiffness grades and four thickness options for the ideal setting of the AOE.

Long nozzle guide rod – optimal for nozzle length in 24–32 mm range (for example SR25)

Medium length nozzle guide rod – optimal for nozzle length in 20–24 mm range (AK, AR15 or similar type)

Short length nozzle guide rod – optimal for nozzles shorter than 20 mm (for example EVO III ASG)

Increased tappet plate stroke length compared with standard cylinder heads

Allows for the use of up to 1 mm longer nozzle in order to provide a tighter fit between the nozzle and hop-up bucking during shooting

Removes potential feeding issues while retaining perfect tightness between the nozzle and hop-up bucking during shooting

Unique system for the mounting of the cylinder head inside the gearbox makes this cylinder head a truly universal solution for V2 and V3 gearboxes from different manufacturers

Mounting pin holes are designed for optimal fit into the RetroArms gearboxes

Rubber impact pads made from polyurethane (PU) rubber with 70, 80 and 90 sh hardness with maximized impact area - 3 mm thickness

70 sh for springs of up to SP130 strength

80 sh for springs of up to SP160 strength

90 sh for springs of SP170 strength and higher

For high fire rate and high-capacity guns (for example machine guns), where 100+BB bursts can be expected, we recommend using a spring one level weaker than stated above (e.g. maximum spring strength of SP120 for 70 sh hardness)

Available also in version without the impact rubber pad in order to be used with other available PU impact pads or Sorbopad in selected hardness, according to selected spring and pad height in order to adjust AOE

Compared with Mk.I version, Mk. II has an added H+PTFE surface finish, longer nozzle pilot, adjusted nozzle pilot diameter and reworked impact rubber pad design for a more efficient impact force distribution

Made from EN AW 7075-T6 aircraft-grade duralumin with proven H+PTFE surface finish for ideal sliding properties while retaining high abrasion resistance of the surface

The Impact rubber pad is made from polyurethane (PU) rubber in selected hardness and O-rings are made from NBR 70 sh

Made in the Czech Republic

Attention: We strongly recommend affixing the grub bolts using a high strength thread locking glue.
