If anyone wants it here the code
P07-AXHEW-9J9VW-11
No clue how I got this but I do, so thoughtd I'd share lol
Also works in every mode even end game and MP so might be pretty good
Edit, my code doesn't work but if y'all dm me I can tell you can have this, I am unsure if it works for anything other then pistols but it probably does to have extra attachments
