Wood is your best bet unless you have access to plastic moulding equipment.
You just need a rasp, chisels and alot of sandpaper (Iused 120grit through to 600)

Here is the stock I made for my comp gun.

looks like the competition will be tough...

you could carve the shape you want out of wax, the make a plaster mold, then use whatever you want to the stock be made out of to fill the mold.

Yes, but finding that something is the hard part. You need to use either resins and hardeners which are very expensive. Or I think there is a method where you make a sort of paste out of small strips of fibreglass and hardener.

25mm flat steel? folded up to resemble the shape of one, and a little bit of foam duct taped to the end.

*EDIT*

something like that, works really well.

wood is the best i think... just like freaky said plus a plane if u got one. sharp tools are a must and if u got the time... sand it down really well and cover the whole thing in body filler u get from auto stores to do spot panel repairs on ur car. it will give it a nice smooth uniform feel without adding to much weight. on top of that... it will make the stock a breeze to paint. unless u like the old school stained wooden stocks :D

Bondo...come on, that stuff rocks. Ive made so many replica stocks and guns from that stuff, and if you screw up, you can fix your mistake with bondo easily.

Bondo is pretty damn strong and hard, though I tend to build a basic support frame (which resembles the stock im making), out of 1/4" copper tubing and card board, and this I apply my bondo too. Ill put a pic up of one i recently did if i can get a chance.

Why not stop at the part before you fill the mold, and instead melt the wax and split the mold in-half lengthwise/vertically (so that you have two identical halves when opened. After you opened it, you use fiberglass to make two halves of the mold and glue/bolt them together.

I like skinner's idea about using steel. You could even put some sheet metal over it, if you dont like the "tactical" look. That all depends on if you have the tools and the know-how for metal working though. Bondo could work, but it can get brittle, and it can also chip/crack. On nice thing about bondo is that you can sand it so smooth, that you will think you are touching glass.
