Very cool.

How do you like those weapon builder tools to push the barrel out? Worth the money? Thanks.

Depends on if you plan to do a lot of work or a little...
I plan to use them quite a bit... so it is a worthwhile investment otherwise you can rent the tools from them as well.
I think it is probably $125 for a week for most things.

Keep in mind this setup is not MP5 specific even though marketed as such it works for all 90 series....

Wish there was a better solution for holding the receiver for the pin.. I used this drill fixture...

One important tidbit and you can probably see in the press photo the guide insert has a trough milled in it to clear the Bolt Carrier Sear Trip denial block in Zenith and MKE and MAC receivers.
The Sp5s have different denial blocks at different points. so you would maybe need that mod or maybe not.
