I'll try to leave my opinions in that other thread, but I have a feeling that many people that argue about guns have never unloaded a 30round mag in 5secs into a target. I could be wrong.
OT: M4s are sick weapons, easy to handle, not too terribly hard to clean. Though I do enjoy a handgun at the range. Honestly, the most fun I've had at a indoor range was with a little .22 handgun. It has almost no kick and you can shoot it super fast. But rifles are so awesome with their burst. I like a good shoulder kick every now and then. I remember vividly my times at the range in Basic.
Also, the "you must be American" comment......duh!
