Bug:
M870 shotgun with Foregrip ejects 2 shells when you aim down sights and shoot. The second shell flies to left and up. Obviously this second shell shouldn't exist. I think it can be seen in first person view only.

Here few screenshots:

Here you can see the second shell on the left side of the weapon. It's a very small shotgun shell.

Here the second shell is shown again.

Hey @Action83,

Thanks for reporting this to us. I'll pass it on to our team.
