Sauer 200 is a bolt action rifle introduced by SIG Sauer in 1984[1] and produced until 1993. The rifle was one of the first consumer rifles with easily replaceable barrels.[1] Sauer 200 has also been sold in Scandinavia under the name Carl Gustaf CG 4000. In 1993, Sauer 200 was replaced by its SIG Sauer 202.[2] The two rifles have many similarities, and for example, barrels are interchangeable.
