Simple, easy to build knex gun based on the Mini-Uzi. This gun fires white rods and has a working magazine.
Magazine + Magazine ram
Step 1: Barrel/Breech
Build all the parts first, then assemble as shown in the last three images.
The update is on the fifth image
Step 3: Ram
NOTE: The bands go through the hole in the middle - bands must be snapped, fed through hole and then re-tied.
Step 5: Magazine + Magazine ram
NOTE: The second picture shows what the two black and white things are in the forth picture. (Top, center)
Updates are shown in the last three pictures
Step 6: Forward grip
I know that actual mini uzi's don't have handles like this but it just makes it easier to aim.
Step 7: Assembly
Step 8: You're done!
And hopefully. you haven't gotten stuck or confused. If you have, just let me know and i'll give you a hand .
