Alright, I don't have pictures but it is so easy you don't need them. You need:
-Some 1/2"PVC
-One 1/2" PVC 90 degree elbow (not pointed at the top, rounded)
- Two 1/2" PVC end caps.
- One larger gun (LBB, Blast Bazooka, etc.)
1) Take some 1/2" PVC or something close to that and cut it longer than where the gun handle touches the ground. This may take a few tries but if it is just right, you will know. I use my power saw to get great cuts (not recommended for younger kids).

2) Take a very long screw ( mine was about 5-7" ) that is the same size as a drill bit you have. I had a 3/8th drill bit and 3/8th screw, worked great. So, take your power drill and drill bit and drill a hole directly through 90 degree elbow, make it as straight as you can. Take a screw toggle wing, as seen below, and spin it onto the screw on the opening of the elbow. It should be on the right outside of the "L". Make this as tight as possible and maybe even glue it.

3) Paint it before you put it on the gun if are you planning to. If not, just attach everything together and drill a small hole in your gun for the screw head.

This is a cheap, quick, and easy way to make a bi-pod for your favorite gun. WARNING: Doing this does not allow the bi pod to fold up. As soon as I figure that out, I will have a writeup on that too.
