When I first used the gun it was fine. Then when I started doing the arena, I spawned with it missing a barrel. It returned just before the match began. Fast forward a few days I go to use it and the same bug happens in campaign and online but this time it doesn't fix itself and I am still missing the barrel for my gun. Itllooks rather funny but it annoys me. The gun works and the scopes work, but it looks awful. Please help.
