Re: paratrooper (airborne infantry)...
Oh Larry,
You say, >"I suspect I know a lot more about guns than you."
Larry can you say, hubris?
Another unwarranted assumption by the conservative contingent. Such fun!
Obviously, what you suspect, you don't know. And that which you know, you can't suspect. In other words you just don't have a clue--and you are making that apparent.
As to converting semi to full auto weapons, I reiterate, ANY gun show will sell both the instructions and at a separate table the material to do just that. Not hard to do, no risk of getting caught at the gun show, a third of the patrons are probably law enforcement of some type or another in civies.
BTW, you are not the only one with military experience.
