Shell ejecting models

For what it's worth, or just as conversation fodder... I've got a shell ejecting MP5 that stopped working and I could never get fixed. Anyone want to buy it off me and take a stab at it? I think what happened was one of the hoses just popped off due to too much pressure or something, but then I took it apart to try to fix it, and could never get it fixed. Pretty damn sure it's all there, and nothing's actually broken, just not attached properly. Cost me like $300 when I bought it used, and it was nice in that it could eject real 9mm brass.

I've got their Walther MPL also, and just need to try to bend or extend the ejector a little- it misses the rim of the casings, so isn't really working either right now. Sadly, that one won't work with real brass.

I've also got a shell ejecting airsoft GBB uzi that is more accurate in its mechanics- actually chambers a dummy round, fires a bb that's stuck in the front of it, then ejects the round. Sadly, this means it jams more, and when it does, it usually ends up chipping or breaking the plastic and rubber dummy round, since it's steel parts and cold gas. Feels great, and is awesome when it works, but I wish there were perhaps metal dummy rounds I could use in it that might make it work more smoothly than with the plastic casings. The rims are thicker than on metal rounds, and some of the other dimensions are a little unusual.

I have a shell ejecting spring H&K P7 that's an unusual mechanism... you cock it by pushing the slide forward. Pull the trigger and the slide goes back, ejecting the round. As a prop this makes it of limited use, as it always looks like you're firing your last round and are left with an empty gun, the slide locked back. Ah well.

Other shell ejecting guns include the bolt action Super-9s (been wondering about making an extended magazine for that, to replace the rotary mag with something more military looking), the D-Boys KAR93 (that's a nice one), and the electric shell ejecting M4s. Those are nice in that they also fire a cap, loaded in the back for the round much like a modelgun, but since the mechanism is an electric motor, it rarely jams. Unfortunately they're pretty cheap looking plastic, semi-auto only, and the magazines are smaller than they should be. I've done minor mods and painting on some of those.

Happy to provide pictures or more info on any of these.
More than happy to get advice on fixing or tuning up some of these.

What manufacturer made the MP5 model that you mention? Is it a metal model, and do you have any pictures of the casings it ejects please?

Tokyo Marui made the MP5 and MPL ..the shells look like 9mm casings only made of plastic and a little thicker than brass.

Both guns are 98% plastic

DOC

Ah yes, the old classics! Many thanks for shining a light Doc, much appreciated.

Just for further info:
The mechanics of the internals of those two TM models have absolutely nothing in common with their real steel counterparts.
There is nothing like a bolt moving back and forth, the ejection port is just open all the time, and a small lever flicks out the cartridges from a seperate slot in the magazine.

I can post some fotos lateron.

@ Fight Designer: Might be interested in that MP5, will drop you a pn soon.

Marushin shows nice consistency in releasing shell ejecting GBBs
