Upgrade set ZERO ECO CUP for manual sniper rifles CYMA M24 CM.702.
The ZERO ECO CUP set is a simplified version of the classic AirsoftPro Upgrade ZERO set, designed for the classic 7 mm spring. When developing it, we focused first and foremost on the quality and performance that is standard with AirsoftPro parts. The second goal was to find a solution that would allow for a lower price while still maintaining the required parameters. The result is a durable and purist design - only three piston components for simplicity, reliability, durability and low cost.
The package includes essential upgrade parts to increase the performance and durability of your gun.
PISTON
- The body is manufactured by precision CNC machining from highly durable 6061-T6 (Dural) aluminium alloy with a high quality anodised finish.
- Funnel-shaped rubber piston head - CUP with large contact area for maximum sealing and cushioned bump.
- The shape of the head ensures a large contact area with the cylinder wall, but at the same time a smooth and easy cocking. There is no metal to metal contact, the cylinder does not wear out and there is less friction.
- As the pressure increases during firing, the rubber presses even more against the wall and a perfect seal is achieved without air loss.
- Designed and assembled in the Czech Republic.
- When assembling, it is advisable to lubricate the head with silicone oil or apply a thin film of Vaseline to the inner wall of the cylinder.
- Dimensions: length 119 mm, outer diameter 21.7 mm, inner diameter 11.5 mm
- Weight: 30 g


SPRING GUIDE

WARNING
When using stronger springs, we strongly recommend installing additional upgrade parts (steel cylinder, cylinder head, trigger mechanism). Strong springs increase the stress on the internal parts, the performance gain is no longer great, they are difficult to cock and there is a risk of damage to the gun.
We are not liable for damage to the weapon due to the use of a very strong spring.
