The Model 76 is the basic Dakota rifle (just about all Dakotas come with a long list of optional features, so you can have yours made very plain, very fancy, or anywhere in between). It also comes in African and Safari models with iron sights and "dropped" magazines that hold four big cartridges instead of the standard three.
The Traveler is a takedown model that assembles and disassembles without barrel threads (which can wear loose over time) and can be packed in a suitcase along with extra barrels of different calibers.
The Model 97 Hunter series is designed for the most precise shooting and utilizes a round-bottomed action. The series comprises the Long Range Hunter, the Lightweight Hunter (well under 7 pounds and, with a fiberglass stock, the least expensive of the Dakotas), and the Single Shot Varmint Hunter.
The Model 10 Single Shot Falling Block is a rifle boiled down to the absolute minimum, as slender as a swagger stick, and one of the most beautiful firearms produced by anyone.
The Double Rifle is an adaptation of Dakota's round-action side-by-side shotgun, which I will get to in the next sentence.
