NZ airsoft FPS limits, explained.
There's no single national FPS limit in New Zealand, every field sets its own. Here's what the numbers mean, the typical ranges you'll see, and how chrono testing works.
What does FPS actually mean?
FPS stands for feet per second: how fast a BB leaves the barrel. It's the standard way airsoft replicas are rated for power. To keep numbers comparable, FPS is almost always quoted and measured using a 0.20g BB; a heavier BB from the same replica reads a lower FPS but carries the same energy.
That's why some fields use joules instead, a measure of energy that stays the same no matter which BB weight you run. If you see a limit in joules, it's the more precise figure.
Typical FPS limits by replica type
These are common ranges at New Zealand fields, measured on 0.20g BBs. Treat them as a guide, not gospel:
- Indoor / CQB AEGs: ~328–350 FPS, close quarters means lower limits for safety.
- Outdoor AEGs: ~400–450 FPS, the most common skirmish category.
- DMRs (semi-auto marksman): ~450–500 FPS, usually semi-only with a minimum engagement distance.
- Bolt-action snipers: ~500–550 FPS, single shot, with the largest engagement distance.
Chrono testing: how fields check
Before play, most fields will chrono your replica, firing a few shots through a chronograph to confirm it's under the limit. Come prepared:
- Bring the BB weight the field chronos with (usually 0.20g).
- Build a little headroom, a replica that reads right on the limit on a warm day can creep over.
- If you run a higher-powered build, know its category and the rules that come with it.
Minimum engagement distance (MED)
Higher FPS comes with responsibility. Fields pair powerful replicas with a minimum engagement distance: if an opponent is closer than that, you can't fire at them. Instead you call a "bang" or switch to a lower-powered sidearm. It keeps high-energy hits off players at point-blank range.
Does more FPS make you better?
Mostly, no. Past a certain point extra FPS adds energy but not effective range or accuracy, your hop-up tuning and BB weight do far more for how your shots fly. Chasing big numbers usually just limits which fields you can play and how close you can engage. Tune for consistency, not bragging rights.
