The Sauer 202 is a lightweight bolt action rifle that was manufactured by Sauer & Sohn in Germany between 1993 and 2015. In the USA, the rifle was distributed by SIG Arms and enjoyed great popularity there as well. The Sauer 202 has a modular design that allows for easy replacement of components and therefore easy caliber changes. The Sauer 202 features a modular barrel change system that makes it easy to switch between calibers.

The standard receiver is made of steel, but there is also a lightweight aluminum version that weighs 470 grams less.

Not without controversy but very popular with a large number of hunters is the Sauer 202's innovative safety, which acts on the firing pin. The safety pin is located directly in front of the trigger blade, and the trigger finger can press it upwards immediately before firing. The safety bolt, on the other hand, is located above the grip, on top of the butt neck, and is pressed upward when the safety is released, revealing a red marking. To lock, the safety bolt is pressed down with the thumb - for many hunters, this is the most intuitive safety of all.

The Sauer 202 features a back trigger for highly accurate shots, for which the weapon is famous.

The successor to the Sauer 202 is the Sauer 404.
