First of all, this is my first k'nex gun instructable, I know it's simple.
Second, I give Oblivitus full credit on the handle and trigger.
It has a removable mag, for grey connectors.
Step 1: Mag
The removable mag. Tape the green rods so that they can hold the sides together.
Step 2: Mag Holder
The part of the gun that holds in the mag.
Step 3: Back Part and Trigger
This part is from Oblivitus's SLIM shotgun.
Step 4: Connecting, Ram, and Mag Ram
Connecting both parts and building the remaining stuff, not including the front grey connector part.
Step 5: Finished!
You're finished! I'm not responsible for injuries.
