I have discovered something interesting about this bug. Remember the bug where at certain angles in 3rd person you cannot see the attachments? It would seem that we have a different bug, but we actually have the same one. And actually, you can't see the attachments from certain angles in 3rd person, even if you think you can. Let me explain this. The angle at which we can not see our gun attachments is the angle facing where our players body is facing (unlike other people experiencing the bug). To test this, put your gun in your hands, go to 3rd person, then hold ALT to barely pan to the right (or barely look left). You want to be looking at your player from almost directly behind him, but just turn your view enough so that you can see his gun. When I did this, my gun attachments were invisible until I was almost looking at my player from the side. The only reason we can't see the gun attachments in 1st person ever is because we can only see our attachments while not looking straight ahead, and there is no way to see our gun at any other angle or from any other point of view while in 1st person.
