pT_LILReckz wrote Just a glitch I found today while prestiging my weapon so have a go as it helps.

I was playing around and made a mistake and found out a really helpful glitch to rank up my weapons fast and also get my favourite guns to 2 prestige, thought I would share with you all

So for this you will need
Max level weapon

What you want to do is make sure you have all the attachments you want on the gun as once completed you won't be able to change until you have unlocked it again.

Once completed you want to prestige the weapon then quickly close application and start the game again, when you log back online the weapon should be prestiged and you should have all attachments on that weapon you choose before.

Please note this was done on PS4 I have no clue if this works on XB1, but this is a easy way to gain 20k XP just by getting your gun back to max level again

Hope I helped and enjoy
