Description

The combination of uncompromising manufacturing quality, which ensures perfectly smooth surfaces, and unique H plus PTFE surface finish allows for a maximally fluent operation of the nozzle. The material used for the construction – aircraft-grade duralumin with H plus 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.

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

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 plus 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 plus PTFE surface finish, longer noz..
