Many players love the SIRIUS series for its sleek design and reliable performance. But what if you want more power and durability without buying a whole new blaster? The good news is—you can easily upgrade your existing SIRIUS with just a few parts. In this guide (with an included tutorial video), we’ll walk you through the exact steps.

Step-by-Step Upgrade Instructions

Step 1: Remove all screws from the body.

Step 2: Remove the screws connecting the gearbox to the body.

Step 3: Use pliers to carefully remove the spring from the tail of the gearbox.

Step 4: Remove the screws from the outer shell of the gearbox.

Step 5: Replace the original plastic tube with a stronger aluminum tube.

Step 6: Re-assemble the gearbox and replace the old spring with the new upgraded spring.

That’s it—you’ve successfully boosted your SIRIUS blaster!

Why Upgrade Instead of Buying a New One?

Upgrading allows you to:

• Enhance performance (higher FPS, better durability).
  
• Save money compared to purchasing a new blaster.
  
• Customize your build to match your play style.
  

With the right parts, you don’t need to replace your whole blaster. Just swap out the components and you’re ready to level up your game.
