PolarStar Air Nozzle — Fusion Engine EPAR (V3 G36, Red)

Precision velocity control for your Fusion Engine G36 build

Upgrade your PolarStar Fusion Engine with the PolarStar Air Nozzle (V3 G36 — Red) — a CNC-machined, drop-in nozzle engineered to tame velocity, improve consistency, and deliver rock-solid performance in Ver.3 Fusion systems and G36 series AEG rifles. If you run a Fusion Engine and want predictable FPS numbers without constant tuning, this nozzle gives you mechanical control over maximum velocity while fitting cleanly into your build.

Why this nozzle matters

The nozzle is the critical metering interface between your HPA/air system and the BB — tiny changes in length, bore, or seal can swing FPS and consistency dramatically. PolarStar’s V3 G36 nozzle is manufactured to precise tolerances so your Fusion Engine behaves predictably: better air efficiency, repeatable velocities, and easier tuning at the chrono.

Key performance (0.20 g BB @ 120 PSI)

PolarStar publishes practical maximum velocity benchmarks so you can match parts to your desired setup:

• 275 mm inner barrel → ~500 FPS

• 380 mm inner barrel → ~550 FPS

• 509 mm inner barrel → ~590 FPS

Those numbers represent expected maximum velocity at 0.20 g BBs and 120 PSI. Use them as a baseline — actual field numbers will vary with BB brand, hop-up, and regulator settings — but they’re an excellent, honest guide for building a compliant and tuned rifle.

Precision engineering & fitment

• CNC machined for razor-tight tolerances and consistent internal bore geometry — no hand-fitting required.

• Easy to install: designed for straightforward replacement in PolarStar Ver.3 Fusion engines and compatible G36 series AEGs.

• Nozzle color: high-visibility Red for quick identification during maintenance or if you run multiple nozzle lengths.

• Bore size: 0.1610 in. — precisely controlled to stabilize airflow and shot-to-shot repeatability.

• Nozzle length: 1.895 in. — optimized for the Fusion V3/G36 geometry to ensure correct engagement and feeding.

• O-Ring specs: external O-ring 014-70D and internal O-ring 7mm x 1.5mm-70D, chosen for seal reliability and long life under high-pressure cycling.

What this gives you in the field

• Predictable maximum velocity — build to chrono numbers you can rely on and keep matches compliant.

• Improved air efficiency — better sealing and flow reduces wasted air between shots.

• Consistent shot-to-shot performance — uniform nozzle bore and length reduce velocity spread.

• Quick servicing — color coding and drop-in fit make swaps and spares easy during events or in the workshop.

Recommended use & tuning tips

• Use the published FPS figures as a starting point. Fine-tune regulator pressure and hop-up after installation to lock in your desired FPS and accuracy.

• Match inner barrel length to your performance goals: shorter barrels for CQB, longer for range. The nozzle’s numbers help you predict the outcome.

• Inspect and lightly lubricate O-rings during installation to ensure a perfect seal and extended O-ring life. Replace O-rings if nicked or swollen.
