An airsoft one is not the same and a sling does not serve anything but to make it easier to carry (they will still annihalate your arms.)

The point is that the trivia is talking about how amazingly unrealistic it is (in comparison to other in universe weapons.) A sling does not eliminate recoil, it just makes it so you can actually lug the thing around.
