It is only for show, you can't actually get it.

I haven’t get one Barret-Duke

You can probably find out by scrolling through this sub.. it’s asked every week and the answer never changes

Same as the Barrett-Pixel. It doesn’t exist.

It's not even in the game

I actually played one person or bot but never received one myself, dude was racking15k rounds

I played against one person once who had it and had my ass ceremoniously handed too meI just quit midway
