(For reference, this is an image from our Toy Galleries showing the guns in their original position. ~Superquad7) This is an older "work in progress" from a few years back: I can’t remember if I removed the spring. I used a styrene piece, or u can use a Q-tip stick. The other rifle is a modified combination of both, with a LED. This is made more to look like Generation One Rodimus Prime rifle.
