Visual issue with “Lights Out” bundle when aiming

I’m opening a hub regarding an issue with the ‘Lights Out’ bundle I purchased. The bundle looks awful when aiming, which really disrupts the visual experience. If I switch to the underbarrel, the problem disappears, but then I have to change the weapon setup, which I don’t want. I happily spend money supporting the game, but I expect more. I requested a refund, but support couldn’t help. I would really appreciate it if this could be fixed, as right now it just ruins the aiming experience
