I guess first off I have to say as an owner of a F/A M16 is there really a need...NO! It is more of a toy and a damn fun one at that. The point is as others have stated is nobody should EVER be allowed to question what another person chooses to own.
Hell if I got rid of all the things I didn't NEED I would have one really crappy life. I have a firebird street car with a 454 that puts out 650 HP do I need it....Nope. I have a Harley do I really need it...Nope.
One last thing my M16 is select fire I can shoot it in semi also. It's just nice to have the happy switch for when the zombies come. [pirate] [postal]
