Another good use of this little device is to turn a flare gun into a hand held shot gun. .... I could in a matter of seconds turn my flare gun into a very leathal weapon.
Flare guns are not strong enough for the pressures of shotshells. It would probably explode and maim or kill you.
When you test this out, I suggest using your left hand (assuming are right-handed) so you’ll still be able to sign the check paying the hospital for the surgery sewing up your new left stump.
Don’t shoot shotgun shells and they will fire at least a few rounds. There is a test complete with pic’s floating around on the ‘net but I can not lay my hands on it atm (at work) The flare guns fail, but they break apart where the front trigger guard meets the frame. The barrel stayed intact in the tests.
Not something I would want to fire personally, but considering the ease of manufacture and the unregulated nature of the flare guns themselves, it’s not an idea I will be forgetting any time soon. :-)
