K'nex MP40





Introduction: K'nex MP40

This is my K'nex MP40 that I just finished making. I was looking for a gun that no one had made before and this was the first one I found, so I decided to go right ahead and make it.

The only copied part is the trigger from TheDunkis's AK47 and i modified a little bit his handle.

This is my first instructable so lots of constructive criticism!

- Durable
- 25+ round magazine

Step 7: Loading and Firing

    dont listen to him. some of your guns are great.

    My MP-605 SMG performs better than this gun.

    Didn't shoot well..... probably just my dodgy visual capabilities (what ever that means). Still a pretty awesome gun, i customized the mag so it could be removed but not enough pieces for another mag. >:-(

    couldnt make the mag work. plz help some one
