Polarstar HPA Engine

Which Polarstar HPA Engine Should You Choose?

All FPS figures are measured with our standard 180mm 6.02 inner barrel and KA Tech's tuned hop-up, bucking, and regulator combination.

Kythera

250–400 FPS · 350 FPS @ ~100 PSI · Semi-auto only

Purely mechanical — no electronics, no full-auto. Just air, BBs, and go, with a realistic trigger pull, break, and reset. Great for training, Milsim, or fields that are hesitant about HPA rifles.

Jack

250–410 FPS · 350 FPS @ ~100 PSI · Up to 50 RPS full-auto

Our entry-level HPA engine. Fast semi-auto with real full-auto capability.

F2

250–440 FPS · 350 FPS @ ~100 PSI · Up to 85 RPS full-auto

The best overall HPA engine on the market — the strongest combination of air efficiency, accuracy, range, consistency, and tune-ability.

Fusion Engine

250–500 FPS · 350 FPS @ ~55 PSI · Up to 75 RPS full-auto

The powerhouse. A clicky tactical trigger board delivers crisp trigger response for players who want the most power out of their rifle.

Our recommendation: First time going HPA? Go with the Fusion Engine. If you're committing real money to get into HPA, go all the way the first time so you're not stuck upgrading piece by piece down the road.
