Unfortuanately i do not have much on this one but as it belongs to one of the main characters and it is one extraordinary weapon i decided to include it. At this point i also think i will include few more GHG guns , but that will be definately later. Anyway if you ever look up a stungun on any site or search engine you will for sure not get anything that looks like this gun. The stungun here is a hybrid in between a gattling gun, glycerine gun and i guess a stungun, even though it looks like a stun the least. Stungun is for sure a damn massive weapon as it ranges about 2-3' in lenght and weighs somewhere over 50 lbs. to this can be also acredited Milly's unbeliveable strenght through out the anime! the gun itself has a load of only 8 shells, but they pack a sure stun on the hit!. Here is good breakdown pic of the stun gun which can help understand it a bit better!

On this pic it is much easier to see that resemblance ot a gattling gun. Also this is a short range gun, and i mean short range, and it has no detailed aiming device. It can shot the stun shells semi-rapidly, as there is a slight break in between everyone while they reload into the main barrel and lock-in. Also the shot jerk is very strong and Milly has no problem handling this but anyone else could be nailed to the wall behind them after firing one of these. On the far right part of the pic is the firing mechanism, which has except the trigger a manual reload lever! In addition to that few other distincitve parts are the carrying handle and a compression chamber that takes out about 80% of the middle part of the gun!

Here is an action pic of milly with the sungun and Meryl ready to whoop some ass!!
