This replacement kit updates valve components from earlier GK1 production batches to V3+ and V3+R standards, and serves as a direct replacement for current GK1 V3+ and V3+R units.

Choosing Your Kit Version

We offer two visual variations of this kit:

• Option A
• Option B

Both options function identically and meet full V3+/V3+R specifications. While either kit will work perfectly in your airgun, we recommend selecting the option that most closely resembles your existing valve components. Choosing the visually matching kit will make the installation process easier and more familiar.

Important Installation Notes

• Install as a Complete Set: To ensure proper sealing and optimal performance, you must replace all components at the same time using the provided kit.
• Do Not Mix Parts: Mixing components from different kit versions, or combining new parts with your original valve parts, will result in sealing failures and inconsistent performance.
