The amount of bonkers Nintendo Wii accessories cropping up never ceases to amaze, but during a visit to a trade show in Hong Kong, we spotted something that takes things to a whole other level.

Although we've seen gun-motes for the Wii before, a Chinese company at the show has upped the firepower with a 1:1 scale Heckler & Koch MP5 sub-machine gun for the Wii.

However, rather than using Nintendo's own controllers for the gun, the company implemented full Wiimote, nunchuck - and - MotionPlus functionality into it.

With a built-in rechargeable battery that juices up via USB, it boasts a built-in speaker and it will rumble when you get hit in supported games.

The model pictured is for the US market, and the company behind it claims that the orange highlights on the front of the gun is supposed to make it look less realistic, so that players using it won't get shot by mistake, be it by their neighbours or the police.

We're not sure if it actually will ever turn up in retail outside of China, but it might be the ultimate accessory for those that are into Wii games where the use of guns are required if it does.
