If you're running a marker with a Gamma Core drivetrain, you already know how smooth, consistent, and reliable it is. But what if you could take that performance even further? That’s exactly what the Planet Eclipse ST3 Bolt Kit delivers.
Whether you're playing in rough weather, shooting fragile paint, or just want the most efficient shot possible, the ST3 upgrade gives your marker a real performance edge.
What is the ST3 Bolt Kit?
The Gamma Core ST3 Bolt Kit is a direct, drop-in upgrade for all Planet Eclipse markers that use the Gamma Core platform. It includes a soft-tip bolt and a spare insert, engineered to be extra gentle on paint while maintaining the efficiency and consistency you expect from Eclipse.
Why you should get it:
Softer on Brittle Paint
The soft-tip design cushions each shot, reducing the chance of barrel breaks. This is especially helpful when using brittle tournament-grade paint or shooting in cold weather.
Drop-In Compatibility
No complicated install here. Just remove your stock bolt and drop the ST3 into your marker. It’s that simple.
Improved Air Efficiency and Smooth Cycling
The ST3 kit is tuned for smooth, low pressure operation while maintaining tight shot consistency, making it ideal for both tournament players and weekend warriors.
Spare Soft Tip Insert Included
Planet Eclipse includes an extra soft tip insert. Just like it is with a lot of their products, you're getting spare parts just in case!
How to install it:
- Remove the bolt system from your Gamma Core marker
- Unscrew the bolt can (blue piece) from the Gamma Core
- Push on the front of the bolt to pop it out
- Apply some grease to the ST3 kit, and install it in the bolt can
- Put everything back together and you're done!
What is the ST3 Bolt Kit compatible with?
One of the best parts of the ST3 Bolt Kit is how versatile it is. It works with any Gamma Core marker! Here's what paintball guns the ST3 Bolt Kit is compatible with:
-
CS2 and CS2 Pro
-
GTEK 170R and M170R
-
GTEK 160R and the original GTEK
-

If your marker runs a Gamma Core drivetrain, the ST3 is an easy, worthwhile upgrade.
Final Thoughts
The Planet Eclipse ST3 Bolt Kit is one of the easiest ways to get more out of your marker. It’s reliable, and built for players who don’t want to worry about paint breaking at the worst time.
