Auto-Ordnance calls its TAO50 “a revolutionary bolt-action rifle designed to redefine long-range shooting power and precision.” The TAO50 is a magazine-fed, bolt-action rifle.

The procurement project, known as the Extreme Long Range Sniper Rifle (ELR-SR), was intended to replace the Barrett M82 series of .50 caliber semi-automatic rifles and the McMillan Mk 15s.
