Hi 

Up for sale or swap is my kwa mp9 comes with all you can see except for the acetech tracer unit

And the for the bits you can't see is

3d printed outer barrel, 6.03 138mm crazy jet inner barrel with a maple leaf 70 degree hop rubber

it all works well apart from the odd ball coming out at a low fps 

It's will come with the original hop,inner barrel so if you don't like the current set up you could change it or put it back to original 

But any questions please ask 07766 522709 

This mp9 needs to go to someone that is hpa ready or has hpa experience to get the full benefits of this set up 

The tap m4 to mp9 adapter works really well 

I'm in Bristol so local collection preferably or could meet up somewhere but yes I can post

Or swap for a good hpa engine what have you got?
