Rate of Fire (RoF)

A higher-speed motor and lighter gear ratio spin the piston through its stroke faster, but a heavier spring rating resists that speed, so RoF is really a balance between the two rather than a motor spec alone. Battery type matters too — a higher-discharge LiPo sustains motor torque under load better than an older NiMH pack.

Fields rarely regulate RoF directly, but a very high rate of fire changes how a gun is used tactically: suppression over precision, and faster magazine depletion. Support gunners tune for RoF; DMR and precision builds usually detune it in favour of a more consistent, controllable shot cycle.

A number alone can be misleading marketing — two guns rated at the same rounds-per-second can feel very different to shoot depending on how evenly spaced those shots actually are, which raw RoF figures don't capture at all.
