what is the fastest way to leveling up guns

[bitter coyote]

its so hard leveling up guns right now igz but what is in your opinion the fastest way to level up guns

[red shale]

Go to the shuro chi checkpoint, kill the enemies, wipe, repeat. Alternatively you can make a loadout with your crafted weapons and swap to end right before the activity you are doing ends.

The swap thing will only give you around 25% of a level per completion so its really not advisable if you are specifically farming for weapon levels.
