Backdraft Phoenix LMG HPA Engine + 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!

Not sure which nozzle you need? Use our nozzle calculator to find yours in about 30 seconds, or add an extra nozzle in the options above for $20 ($5 off the $25 standalone price), or grab a third for just $15 ($10 off), so you’re covered.

What it does

The Phoenix LMG replaces the motor, piston and cylinder in your airsoft LMG with high-pressure air, for faster trigger response, a higher rate of fire, adjustable power and far less maintenance. It drops into your LMG gearbox, and since most LMGs don’t have an electronic trigger board, we include an adapter that plugs the FCU straight into your trigger switch. No soldering. Belt-fed at 40+ RPS is exactly as fun as it sounds.

FAQ

Will it fit my gun?
The #01 nozzle in the box fits many LMGs, like the A&K PKM. Others take a different length: M249/MK46 models from Classic Army and A&K use #03, and the A&K M60 and CG M249 Featherweight use #14. Our nozzle calculator tells you exactly which one you need.

Is it hard to install?
If you can use a screwdriver and follow a video, you can do it. The LMG adapter plugs straight into your trigger switch, so there’s no soldering, 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.
