There are only two independent gun corporations in which you can buy stock, that is Ruger and Smith & Wesson. Don't know who owns Mossburg. There are probably several privately owned gun companies like Henry, Kimber, or such. Winchester and Browning are owned by FN. Don't know about Colt. I think the anti-trust act could break up the large oil companies also. Look what happened to Texaco, Amoco, Pure, Sinclair, Gulf (in the south), ect. Same with the tire companies. Uniroyal and Goodrich are owned by Michilen now. Firestone got bought out by a Japanese company. There are natural monopolies like AT&T which were regulated. Most of the oil companies and other companies said they needed to merge to become a bigger player in the international arena, but it doesn't promote competition and lower prices that should be with capitalism. We are just not using the anti-trust laws to keep more companies going. They were looking at breaking up GM back in the early 70's. They had 70% market share in America with ford at about 20% and Chrysler 10% with AMC a sliver. They were talking about splitting off Cheverolet which was half of the GM market. Might have made for more competition, better, and lower priced cars.
