Overview: KSC M9 Homemade Bullpup Kit

Before jumping into buying anything, i need to point what kind of difficulties you'll be facing making this bullpup.
Let's start:


- See near m9 trigger and it's lower frame. KS(Echo 1) P90, those site need to remove so m9 can sit inside.

- Upper Part (Railed) Removed. Now you can see ksc m9 sit here. I replace stock inner barrel with ksc m4 gbbr, need little sanding. I'll explain it later.

  

 

- Here's upper part. You see, i just need to flip charging handle, move the handle to opposite side

 

 - Upper part of P90, need to cut to free space when m9 slide move (blowback)

- Use plastik heatgun, to create this holder. This is one of 3 ways to support and keep m9 from moving inside p90 body.

 Those are main work need to be done. I''ll see you for next part "Preparing P90 Body"
