As millions of Americans look forward to hunting season, CNBC offers an expose on the dangers posed by one of the country’s most popular rifles. “Remington Under Fire” (8 p.m., CNBC) begins with a horrible tragedy. While out hunting with her husband in 2000, a woman accidentally shot and killed their 9-year-old son. To add mystery to heartache, she insisted that her finger was nowhere near the trigger.

Fully believing his wife, the grieving father began to investigate and discovered dozens of similar stories of the rifle firing on its own after the safety was removed. CNBC reporters tracked down law-enforcement officials who were well aware of the gun’s shortcomings and referred to such mishaps as “Remington moments.”

In a surprising, almost cinematic twist, CNBC tracked down the original designer of the rifle, a 95-year-old man living in a nursing home. Still feisty and still tinkering on rifle designs, he explains how he warned the company of its trigger problem in the the late 1940s.
