What is Weapon Tuning?

What is Weapon Tuning?

Adjust a Weapon's Attachments

Weapon Tuning allows players to modify the attributes of a weapon and adjust them to a player's liking. Once a weapon has reached its Max Level, players can utilize Weapon Tuning and tweak the attributes each attachment affects.

An example of this are the two sliders for the weight and length of a weapon's Barrel. Tuning the weight slider will affect its Movement Speed and Recoil while tuning its length slider affects both Aim Down Sight Time and Damage Range.

How to Access Weapon Tuning

Accessible in the Gunsmith

From the main menu, head to the Weapons tab, then select Multiplayer Loadout. Once Weapon Tuning is unlocked, a Tune button can be found on tunable Attachments. Select this button to get to the Tuning Menu where you will see a radar graph that shows an Attachment's stats.

Adjusting an attribute will decrease a different attribute on the opposing side so players should keep an eye on which attribute they want to maintain at a high level. Again, Weapon Tuning is only available upon reaching a weapon's Max Level so make sure to progress through the levels to begin modifying your weapons!
