Other info:
Do not use aerosol silicon oil on the bucking it will cause it to swell and BBs will not exit.

Below is an encountered problem I had with the MP7. I would advise checking your bolt every 500-1000 shots to make sure everything is tight.

One of the screws coming out on the side may have been due to the vibration of the gun?

Thanx...I'm still not clear on how to remove the fire selelctor which would allow me to get to the hop-up and inner barrel. I was wanting to put in an extra-long tightbore barrel and then cover it with a barrel extender (preferably a proper H&K MP7 style).

Would the longer inner barrel increase range and accuracy enough to warrant such an upgrade. I'm definately going to put a tightbore in, I just don't know if its worth the headache to install an extra-long tightbore w/barrel extender. :innocent:

In my opinion a tightbore is not worth it.

Accuracy may be minimal, but you will get a definite increase in fps.

Agreed. I just had the EdGI 6.03 put in my MP7. The real difference is with the FPS. I went from a high of 408 FPS to 440FPS with .2's and a room temperature mag. Now my gun fires hotter than most so keep that in mind, but the increase in FPS was what I wanted because I do not use the gun for CQB. It's really impressive to see.:gun:

what about an extra-long inner barrel (tightbore or not) for increased range and accuracy?  :hithearts:

...and help with removing the fire selector?

In short , yes. I think you would gain both. Range due to an increased FPS and accuracy because of the dynamics of a longer barrel. The reason I didn't comment on accuracy with my MP7 is because I haven't actually tested the gun for other than FPS. Though from what I have read and and my impressions from shooting in the back yard, the the TBB standard length does show improved accuracy. A longer quality barrel should do the same. :gun:

accuracy in these types of guns is dependent on the function of the action.  A particularly violent action has a tendency to beat up the projectile before exit.

If your going for TB, stick with 6.03 any tighter and you'll have problems on full auto.

Im thinking of doing the same deal with a 6.03 363 mm Falcon barrel with 220 mm barrel "extension".
The gun is brand new, and I do not wish to do the work myself at this point.  Jotohomomoto, did you ever get the fire selector switch question answered?
Can anyone recommend from personal experience a good tech to do the work?
Of course I will wait for the 45 day warranty to expire first.

CAUTION: The falcon 363mm TBB will increase FPS of the KWA MP7 to 450 fps in the summer. This is probably too hot for most any field.

How is the falcon barrel compared to edgi? Accuracy and range wise.
