Hello all, its been a LONG time.

I am about to obtain this POS gbb in a trade. Why would I trade for this you ask? Because I'm givng the guy a KSC Glock and hes giving me cash + the MP5 with 3 mags (2 leak), so I figure it'll be a fun easy way to play around with a factory style gbb system.

I know it is a POS, but to my knowledge the one I am getting is functional (even if its not I plan to rip into it anyway). So those of you that have taken them apart or at least know how they work, what would you do to one of these if you had no worries about destroying it? My reasoning for settling on a little less (cash) is that it has been a very long stading goal of mine to do a complete custom build for an SL9. However, until I get tools time and money... mainly tools, I'm just tinkering and learning.

I have quite a bit of experience with DIY airsmithing and designing, so I'm open for trying anything on this as long as its cheap. (Just tapped myself out building some real guns, so this is gonna be on a budget). I look forward to hearing your input!

I love these builds.

I had a GBBR that I got for free one time and here is what happened.

I piped the external air directly into the mechanism, converted it to use AEG mags (like a DG), then I changed the bolt a little bit so it would be a closed bolt mech - the gas is stored in the bolt and there is just one valve before it shoots the bb, and then I dropped the whole thing into a nerf rifle just for kicks. It could shoot bbs and nerf darts.

It was a lot of fun.

Sweet! I have no idea how this one specifically works... but I want to try and incorporate a few of the qualifications that I am going to require in my eventual SL9 build.

One of the reasons I haven't really started on the SL9 is because I dont have a lot of exp prototyping with gas stuff, mainly mods and building conventional designs from scratch. That and the qualifications I have for the build are kind of strict:
AEG mags
External air
realistic recoil
semi auto
no pilot air volume
ideally all mechanical, no solenoids, although I go back and forth on this one.

So hopefully Ill be able to work some of those into this. Heavy recoil on something the size of an MP5K would be awesome...

To be honest I'm not familliar with that one, although I have tried to do as much reading as possible on classics and the WA2K. The pictures from Woogies thread here http://www.airsoftsniperforum.com/showthread.php?t=4036 pop up on google, but they don't load on the page.

Perhaps in mechanism it may be what I'm looking for. But in over all scope I want to make the hop-up and barrel mount as a part of the engine to implement a hop up design I have been playing with. Not to mention that the greatest aid to accuracy is repitition, and having multiple key components that aren't physically attached (i.e. aeg hop up to MB) doesn't really aid accuracy much.

Yeah, the WA2K uses a solenoid, but if I went that route I'd follow that design more closely than say the P*.

And it turns out the guys brother broke the MP5. I told him I'd take the parts since I was going to rip into it anyway, but he was convinced it was toast so he didn't even bring it. Oh well, I guess it's back to waiting....

Edit:
Cheese, if you have a link to a thread that details the kokusai that would be awesome. IMHO the sport took/was forced to take a turn for the worse when AEGs came around, so I'm really trying to think/find a way to blend modern hop ups with some kind of minor step up from the classic platforms; so the more I can find the better. But unfortunately fate has a way of taking its sweet time, so it's been a long process lol.

Yes the Asahi uses solenoid, the P* engine is very similar to the Asahi!

Your best bet is to use a Crimebuster engine as Cheese man suggested or you could use a DG GBB engine modified for the SL9.

I'll probably will start soon messing with my Geneth WA2K and this thread is just perfect for giving me ideas!

Wolf, I was under the impression that the WA2K used a linearly mounted solenoid that move the piston, and the piston had a sealing face on it; whereas the P* basically uses an off the shelf type solenoid. Not to mention the BB feeding is way different, allowing the WA2K to have a potentially much more efficient system.
