How Freedom Group Became the Big Shot - Lined up in a gun rack beneath mounted deer heads is a Bushmaster Carbon 15, a matte-black semiautomatic rifle that looks as if it belongs to a SWAT team. On another rack rests a Teflon-coated Prairie Panther from DPMS Firearms, a supplier to the United States Border Patrol and security agencies in Iraq. On a third is a Remington 750 Woodsmaster, a popular hunting rifle. The variety of rifles and shotguns on sale here at Cabela’s, the national sporting goods chain, is a testament to America’s enduring gun culture. But, to a surprising degree, it is also a testament to something else: Wall Street deal-making.
