Fire rate is the frequency at which projectiles are launched per second. Various mods can be used to increase or decrease the fire rate of primary and secondary weapons. This applies to bullets, lasers, arrows, and hand thrown projectiles.

Mods that increase fire rate also reduce the spin up time of spooling weapons which includes the Gorgon, Deth Machine Rifle, Soma, Cestra, and Supra. They also reduce the charge time of bows and other weapons with charge such as the Ogris, Miter, Stug, Ballistica and Lanka. For burst-fire weapons, such as the Burston and Tiberon, fire rate affects both the speed of the burst as well as the time between bursts from Hotfix 17.4.3 (2015-09-16) onwards. Continuous weapons such as Ignis and Flux Rifle have no additional visual effects from fire rate mods, however they still do damage at an increased rate. Increasing fire rate on semi-auto weapons increases the cap on how fast they can fire and vice-versa. On duplex-fire weapons, fire rate mods affect the time between each 2 round burst, similar to burst-fire weapons.

High fire rate exacerbates the effects of weapon recoil. For some weapons, lowering the fire rate can improve the player's overall accuracy.

Fire Rate Mods

Dual-stat fire rate mods are obtained from Nightmare Mode missions. These mods combine increased fire rate with another positive enhancement. These mods are often weaker than their basic counterparts, but are useful for stacking or diverse builds.

These mods are found within vaults of the Orokin Derelict missions, increasing fire rate at the expense of other weapon stats.

Found in Orokin Derelict missions, these negatively affect fire rate in exchange for other enhancements. Weapons with innate overbearing recoil can be made more effective at range by reducing the fire rate.

These mods are dropped by Stalker's Acolytes during Operation: Shadow Debt. These mods increase fire rate while aiming for a short duration after reloading.

These mods are dropped by Grineer Commanders on the Plains of Eidolon, and may also be awarded by completing Ostron Bounties available in Cetus. They provide additional bonuses based on the number of set mods presently equipped.

These mods are the primed variants of the normal fire-rate mods.

Charged Weapons

For weapons that use a charge mechanic, fire rate mods will increase the charge rate. Note that this increases the speed at which these weapons charge, which is not the same as lowering the charge time directly:

Charge Rate = 1 ÷ Charge Time

The charge rate is the speed at which the charge circle progresses to full. Applying mods works as so:

Modded Charge Rate = Charge Rate × (1 + Mod Bonus)

For the resulting charge time (seconds per charge) this means:

Modded Charge Time = Charge Time ÷ (1 + Mod Bonus)

Auto-Spool Weapons

Some automatic weapons don't start out firing at the fire rate listed in the Codex. Instead, the first few shots are fired more slowly as the weapon 'spools up' to the maximum fire rate. Once the maximum fire rate is reached, the weapon will continue firing at that rate until either the wielder stops firing or runs out of ammo.

Weapons with auto-spool:

Burst Weapons

Weapons with burst-fire

The following weapons have burst-fire as its primary trigger mode or as an alternate trigger:
