First I would like to state that the last gun show that I attended was about 80% military style weapons. If this is indicative of how things are in other parts of the country I don't see how someone in the business could miss this. Maybe Jumbo doesn't go to many shows or read any of the popular gun magazines. They are filled with these weapons also.
As somebody stated earlier, they are fun to shoot. So are the fully automatic ones. I had a chance to go to the automatic weapons shoot at Knob Creek, Kentucky a number of years ago. The people there were having quite a bit of fun. If I could afford the ammunition, I wouldn't mind buying one to play with.
A tweeked AR can be a real tackdriver. Colt sells their AR-15 with a 5 round magazine (or at least they used to) for use as a hunting rifle. When it comes right on down to it a rifle needs to be accurate and the cartridge up to the game that is being hunted. For some game the AR fits the bill. I have used mine to hunt coyote when I was living in Montana. It held up better than my M-700 in that environment.
Another thing to keep in mind is that the bolt action did not become popular until after the GI's returning from WWI started using them. They had been trained on the bolt action and when they became available surplus they were bought by these same servicemen. Today, the younger folks in the military were trained with the M-16. Naturally they would feel comfortable with it and some would want one for a personal firearm.
I don't use my AR-15 as much as I used to. I hunt mostly birds now so the shotgun is my current weapon of choice. I use a .44 handgun or a 45/70 rifle for big game. These are my choices but that SKS I have would sure make a sweet gun for pig hunting.
Zumbo's comments were out of line, probably through ignorance and a feeling of superiority. The old time outdoor writers were brought up with bolt actions. They feel that the bolt gun is a superior firearm and that they are superior because they use them. Personally, I don't like bolt actions, I much prefer lever actions but that is another argument.
