Yes, and it's not one of those dumb movie props, its the real thing! I only had a 5 mw laser, but YOU can put in a 500 watt one so it will cut through metal! (Or should I say "shoot"...) Then, I would advise you to make this out of metal.
Let's get started!
Step 1: Materials
You will need:
1 flip-open cardboard box.
1 tube, preferably metal. (I used plastic, but that stuff bends...)
1 pen-sized laser, or whatever type of laser you want to put in there.
1 glue gun.
5-8 glue sticks.
1 box cutter.
1 red and white flashlight
Step 2: Making the Stock
Grab your flip-open box, and and make a v-shaped cut into the back. Make sure the top can still flip open. Once you have done that, cover that up with cardboard. Also, make a little cut into the back for the laser to smoothly slide into. DO NOT cut it entirely off, but instead, fold it in. This will provide resistance for your laser so it will not slide around while using it.
Step 3: Cut the Tube to Size and Adding Misc.
The smaller, the easier to handle. I worked with about a foot and a half. (0.457 meters)
Make sure the tube is as straight as possible. After you cut it, sand the ends of the tube so they are flat, level, and smooth. Insert the tube into the box. The one from step 2. Also: add your scope, I had to use binoculars, and cut a box hole in the front for the "Armed" sign.
