Lol, no.

Would you rather have your lower half explode and feel immense pain as you crawl to your last hope, the door (the type that goes up and down), only for it to be shut on your hands to which you lose large amounts of blood and have me as the last thing you see before you die?

Multiple bullets are being shot in the same rounds. What you see is either another bullet or an afterimage.

Not really. It’s just a machine gun disguised as a rifle. I don’t see why you think it’s so OP.
