Given the historic breakthroughs achieved with the Henry rifle, Winchester improved on its design to make it even more useful on both the range and the battlefield. In 1866, they introduced Nelson King's patented spring-steel loading gate, as well as a wood forend for added comfort. These changes led to the creation of the "Yellowboy," - the earliest version of the quintessential cowboy rifle whose lines and basic functioning survive to this day.

The Uberti 1866 Yellowboy Rifle .45 Colt presents the brass-framed lever-action in its classic short rifle form with a 20" barrel and a dependable 10+1 capacity. It balances traditional styling with smooth cycling to recreate the feel of a frontier-era working rifle. This configuration offers a steady, authentic option for cowboy-action shooting and enthusiasts who appreciate historically aligned handling.

The Uberti 1866 Yellowboy Rifle .45 Colt retains the iconic brass receiver and octagonal barrel profile that defined the original 1866 pattern. Its A-Grade walnut stock provides a stable shoulder fit that complements the rifle’s length for controlled, deliberate shooting. The lever mechanism operates with predictable smoothness, giving shooters a satisfying connection to the design’s 19th-century heritage.

The blued barrel and polished brass furniture blend with case-hardened components to create a finish true to period craftsmanship. Its six-groove rifling and 1:16 right-hand twist support reliable performance with .45 Colt while maintaining the mild, manageable characteristics of the cartridge. With a 43.25" overall length and well-balanced 8.2-pound weight, the rifle settles naturally for extended range time.
