How do I Redeem vip guns in game

So I’ve been getting a bunch of guns from the top rewards and was wondering how I claim them or get them is it in the bank the stash or does it just go in my inventory when i play next???

It will go to the backpack of the first character you load. Also the weapon will match the level of said character. It can take up to 2 hours to appear after redeeming a reward from the website.
