ABC hatchet job on grenade lanchers.

Shameful. I guess that's what passes for journalism these days. Get on Google and take the words of the first idiot who picks up the phone as fact.

If you're interested in the actual process of buying a grenade launcher, read this. While there are slight differences between registering a short barreled rifle and buying a grenade launcher, most of the process is the same and it's much more accurate than ABC's schlock.
