This DIY double barrel shot gun is a variant of the improvised shot gun that I've detailed in previous posts.

The original design is based on a classic (1969) method from the US Dept. of the Army Improvised Munitions Handbook (TM 31-210). This drawing is a simplified adaptation of those plans.

Here are a few variations that didn't make it into the sketch:

1. A reader suggested using springs to replace the rubber bands. I haven't tried it, but that sounds like a mechanical improvement.

2. The firing mechanism works much better if you bend the strap into a "U" shape instead of an "L", anchoring the device on both sides of the stock. The double barrel version requires two "L" shaped straps if you'd like to discharge each barrel independently. A larger  "U" shaped strap/trigger will fire both barrels at once.

3. Another reader suggested that I use pipe clamps or bailing wire to hold the barrels to the stock. Great suggestion - if you have those materials readily available. In a RECESS situation, you may or may not. I chose to go with twine for the simple fact that I am surrounded by plants that could be worked into a crude twine.
