Oh for the love of......
Ok, holding a background in engineering and SOME knowledge of firearms, converting an airsoft weapon to a working firearm is not only absurd, its STUPID! I mean, firearms are expertly designed to handle the extreme pressures and temperatures of shooting. Airsoft guns are little more than die-cast replicas with little or no thought given the internal structural integrity. Airsoft, being pneumatic for high-end versions, have only a fraction of the internal pressures and stress of a real firearm. Long story short; anyone dumb enough to do this would likely kill themselves.
Second, if it were possible, WHY TELL PEOPLE HOW TO DO IT??? I mean, if you want to STOP people from doing it, why tell everybody and his brother about it? Eventually, some fool is gonna try it. I propose we press charges against the media for "dissemenation of terrorist training documents"
If I wanted to make a gun, Ill stick with a potato gun!
