Backdraft Phoenix HPA Gel Ball Engine + WIRELESS FCU

When I got into HPA, a name-brand engine cost $300–400 before you even bought an FCU. CRAZY! So I made my own, and it turned out so good I just HAD to share it. Over 50 players have already left it a 5 star review, and if it’s not for you, you can return it with our 30-Day Field Test Guarantee!

What it does

The Phoenix Gel Ball engine replaces the motor, piston and cylinder in your V2 gel blaster with high-pressure air, for faster trigger response, a higher rate of fire, adjustable power and far less maintenance. It comes with an adjustable gel ball nozzle and the Catalyst Wireless, so you can tune everything from your phone.

FAQ

Will it fit my gun?
If your gel blaster uses a standard V2 (M4-style) gearbox, yes. The adjustable gel ball nozzle lets you dial in the fit and feeding for your blaster.

Is it hard to install?
If you can use a screwdriver and follow a video, you can do it. Our V2 install video walks you through it, and our Discord is there if you get stuck.

What else do I need to run HPA?
An HPA tank, a regulator and an air line. Want to try it before you buy a tank? Our Unlimited Air Adapter ($20) runs your gun straight off a home air compressor for testing and tuning.

What if something breaks?
We offer 24/7 tech support, and our Discord has real players who’ve done this install hundreds of times and are always happy to help. Reach out anytime and we’ll get you back on the field.

What’s the 30-Day Field Test Guarantee?
Try it in your gun for 30 days. If it’s not for you, send it back for a full refund. Read the full policy.
