Uberti has recreated the most popular 1866 Rifle models:

Yellowboy Carbine, with 19 inch round barrel and carbine-style brass buttplate
Yellowboy Sporting Rifle, with 24-1/4 inch octagonal barrel, brass forend nose cap and solid brass crescent buttplate

The 1866 Yellowboy Rifle was a marked improvement over the Henry rifle. It became a worldwide hit.

It had a convenient new type of loading gate devised by Winchester plant superintendent Nelson King. It passed cartridges through the side of the receiver. This improvement made the lever action more functional and allowed for the installation of a wooden forend.
