One of the reasons bunji slings were introduced, was for breaching shotguns.

It allows the shotgun to be kept close to the body if another weapon is being used. Then when needed it can be pulled away from the body and put to use.

It was then adapted to other shorter carbines and subguns.

The main problem with bunji slings is that all the cheaper ones, use cheap bunji cord, which has much more "bounce" in it than higher quality slings. This has caused chipped teeth, loss of teeth, bloody noses and other bumps and bruises.

The drawback to single point slings is the majority of the time you have to hang onto the weapon to control it's movement. The bunji helps with some of this again, by keeping it close to the body.

With a MP5 you shouldn't have much trouble with a bunji sling.
