Durable and light upgrade set for spring action airsoft rifles. Package include all what is needed for basic upgrade.

Hybrid Piston

• Made by CNC machining from light, but durable aluminum alloy 6061-T6 (Dural) with a high-quality anodized finish.

• POM ring for better sliding in the cylinder

• Catch back end part made of stainless steel.

• Back-pressure system with O-ring (O-ring expands and seals better when shotting).

• Rubber front pad. The impacts of the piston are so quieter and the impact is spread over a larger area.

• Dimensions: lenght - 117mm, outer diameter - 19,8mm, inner diameter - 13,5mm .
• Weight: 30g.

Spring guide

• Allows the use of classic 7mm springs and stronger 9mm spring springs.

• Axial bearing makes pull back much smoother, because of limited spring rotation.

• The spring guide is made of stainless steel with a perfectly smooth surface.

Spring

• High-quality spring made of spring wire with heat treatment and grinded ends.
• Chemically blackened against corrosion.
• The outer diameter of the spring is about 12.8mm.

Warning: We do not take responsibility on gun damage due to the use of very strong springs. Stronger M180 and M190 springs are hard to stretch. The reasonable spring is about M150.
