How did the NRA transform from a sporting group to a mighty political force?

Compiling newsreels, articles and television news reports, The Rifleman examines some four decades in the history of the National Rifle Association (NRA). Via these archival materials, the US director Sierra Pettengill frames her portrait of the controversial gun-rights group around Harlon Carter, the former NRA president and a US Border Patrol chief, with an overturned murder conviction to his name, who was central in forging the NRA’s transition from a sporting organisation to one of the most potent and controversial political forces in the United States. Tracing the many overlaps between Carter, the NRA and US Border Patrol, Pettengill finds a group that, since the dawn of Carter’s influence, has been propelled by reactionary racism.
