I wouldn't consider any to not have such uses, and that includes arms beyond just "firearms". However the anti arms rights crowd is always blathering about how this or that arm has no legitimate civilian purpose. (Too big, too small, too ugly). Thus the fact that the amendement provides no support for any such restriction is important.
That's the kin of attitude that really helps the pro-gun movement. Thank you. Rocket launchers for home defense -- get yours today.
