We install the Begadi PRO VARIOHEAD (Pistonhead) which makes it possible to adjust the energy of the gun in 4 steps - simple and easy. We also add an adjustment tool in suitable length.

Further information about VARIOHEAD you can find here. (YouTube, introduction video).

Our Begadi PRO VARIOHEAD is an adjustable, CNC machined piston head with which the energy of the weapon can be quickly and easily throttled in steps.

It is therefore not necessary to change a spring or open the gearbox to lower the energy. This is a great advantage for weapons without a spring change system.

In the maximum setting, the Variohead behaves like a normal pistonhead and delivers the full energy of the installed spring. Using the click system and the available adjustment tool, the energy can now be reduced in 4 stages (up to 50%). To do this, the tool is pushed into the barrel from the front until the hexagon is anchored in the piston head. By turning (clicks) the energy is reduced step by step. This is achieved by a small amount (depending on the setting) of the existing air in the cylinder is discharged to the rear.
The setting remains via the click system even with stronger springs and does not adjust.


Features:
- Energy adjustable via steps
- CNC manufactured from 7075 aluminum and steel for AEG/S-AEG weapons
- Precisely and accurately manufactured
- 8 ventilation holes
- Quad ring for best possible sealing to the cylinder
- Front O-ring prevents rubbing against the cylinder and supports the seal
- Built-in ball bearing, which prevents torsion and thus deformation of the spring in the long term
- Adjustment of the AOE by 1.5mm
- Can be combined with all Cylinderheads (small, large Sorbo Pad)
- Very smooth running in the cylinder
- Also suitable for strong springs


The variohead is supplied only installed in our guns, it is not sold separately.

  • A suitable lipo battery is supplied. We take care that the plug fits to the plug of the gun and we also check that all cells of the battery are okay. It is possible that the price of the supplied battery differs in regular shop and is a bit higher or cheaper in regular sale.

Additional information on the warranty + Core:
The 4-year warranty mentioned above refers to the complete Semi AEG when the CORE Mosfet is installed, not just to the function of the Begadi CORE. However, this is the prerequisite for this extended warranty. If, for example, a different Mosfet is selected in the bookable special options in the Mosfet area (i.e. you ask us to remove the CORE and install a different Mosfet instead), the warranty is reduced from 4 years to the usual 2 years. In this case, the removed Core will not be included in the delivery but retained. Normally, we always include removed components in the delivery, but this is expressly not the case with the CORE - the CORE is only delivered in an installed state
