So, I got it in the mail today.  I thought I would start a thread here and post everything I do to it.  Only time will tell if it will work.  I'll test it by itself this weekend before I begin to monkey with it.  I'll post pictures if I can too.

First impression:
I laughed when I inspected it.  On it is a big sticker, under which are full Hk trades, caliber and all, covered by black marker.  I have yet to get the marker off.  I was never a big trades guy but at least I can sell it for a decent price if need be.  I pressed on the inner barrel and there does indeed appear to be quite a bit of pressure from the spring.  That definitely needs to be changed to use this thing for an extended period of time.

What I plan to do:
First of all I'm either going to cut the spring or move the spacer back and sit it permanently.  Second I may or may not try and crown the inner barrel of the supressor where they connect.  Let me know on how you guys would go about this. I'm not going to bother unless I have jamming or accuracy problems though.

Something that came to mind was this, keep this thing off your gun when you are not actually using it.  Modified or not.  Having the gun sitting there with unnecessary pressure on the barrel is no good at all.  I would even go so far as to take it off when you do not need it in game if at all possible.  At least during the time in between.  Just a thought.

If you would succeed at fixing the hard pressure, would you make a tutorial how to fix it? Because I want to get one too but i'm afraid it will harm my MP7

Will do.

Update:
So I got my flash hider off.  I must say, that was pretty easy compared to what people have told me.  Three minutes with a hair dryer and a 10mm wrench.  I was actually afraid I twisted the outer barrel at first because I couldn't feel it getting any easier.  No problem though.  The supressor looks pretty dang awesome. At this point I don't care if it works or not the look will be enough.

I filled up a mag, and fired a few shots with out it just to check that everything was in order.  I put the supressor on and it performed great.  Judging from the speed of the BBs it's easily over 450.  BUT, upon taking it off I was confronted with something that concerns me a little bit.  A small amount of dust.  Yet I did not see a decrease in accuracy.  I fired a bit more without the supressor, then put it back on.  I shot twice on semi and switched to full auto.  The supressor did just fine.  Accuracy seemed bad, but the gun is blowback.  I didn't see anything that concerned me.  Upon inspecting the supressor again there was not a big difference in the amount of dust by the barrel.

It seems to be a very, VERY, fine powder.  I don't think every single BB is losing anything.  Time to open up this bad boy.

The picture makes it appear that there is more dust than there really is.

CORRECTION:  The dust is from whatever KWA uses to glue the flash hider on.  It's not from the BB.  I smashed one and they appear to be slightly different.  I'm no chemist but I'm sure it's just the glue.

So, here is a picture to give you an idea of how much extra tension there actually is.  Notice how little space there is between the end of the barrel and the cap of the supressor, and how thick the spacer is.  The other silver colored spacer that is attached to the barrel won't budge.  It would be a thousand times easier to simply move that but I can't.  There are two little screws on it but after taking them out it still won't move.  I'm convinced it's glued on somehow, and I'll probably break the barrel trying to get it off.

I'm going to go to a hardware store and see if I can find some different spacers I can try.

So, I got 4 5/16" flat washers and duct taped them together.  Definitely less pressure now.  But I'm beginning to think the FPS dropped a little compared to the bigger spacer.  I can't tell without a chrono.  My question to you guys is: If you have used this, did you leave it on your gun when you were not playing?

I honestly think that is what the real problem is.  Not that there is too much pressure on the barrel, but if you let it sit there constantly it probably will shove it back.  As of now, I have the stock spacer, a smaller one, and no chrono.  I'll let you guys know how it goes.

Something else I noticed, I'm not sure how people have had trouble with accuracy.  The stock barrel sits back a bit in the outer barrel, so the extension actually goes into a little bit.  They both should always be sitting perfectly in the outer barrel as if they were one.

i have one. I adjusted the Silver colored spacer by loosing the screw on it so the pressure is not that strong. So far it is a success. The thing with the suppressor is that you cant really attach it quickly because you have to make sure that the inner barrels meet then you have to turn it until the BB's shoot straight.

This thing sounds like a major PITA.  Lets go back to what your original goal was....what was that exactly?

Well.  I'm pretty sure it won't work.  Aligning the barrels isn't a problem.  But over time especially coupled with the blow back I'm sure it'll mess up the stock inner barrel.  I was originally going to adjust the silver piece but mine is not only screwed on but somehow glued or just stuck.  And it's not going to move.  I tried my buddy's heat gun, no good.
