Intro: K'NEX BTM Spiker (Build)
Step 1: Main Body #1
In this step, you will be building the first part of the body. If you have any questions, just ask.
Step 2: Handle
In this step, you will be building the handle. I did not take the handle apart, but it is very easy to build, and I suggest that you mod it the way you want it.
Step 3: Mand Body #2
In this step, you will be applying all of the rest of the internals, and the last side (the left side of the gun).
Step 4: Extras and Banding
This is the last step, and in this particular step, you will be adding the attachment bar, the extras, the rubber bands and the firing pin. If you have any questions, please do ask. =D
