'Automatic Carbine 24'), initially the Självskyddsvapen 24 is a Swedish version of the Finnish Sako M23 assault rifle that is in service with the Swedish Armed Forces as of December 2024.

As part of the Nordic defence strategy, Finland and Sweden signed an agreement in April 2021 regarding information exchange of future procurements of personal equipment of soldiers, followed in September by an arrangement for common procurement and an implementation document in December of the same year.

[4] Therefore in the spring of 2023 the Swedish Armed Forces along with the Finnish Defence Forces, who were also looking to replace their Cold War-era rifles, signed a contract with the Finnish firearms manufacturer SAKO to supply each respective armed force with firearms of the newer M23 family which had entered production just one year earlier.

Implementing the A-variant has already started in the last two quarters of 2024 in four platoons across three regiments and one air wing.

[6] Feedback on the rifle from testing in the Swedish Army has been positive, noting that it is light compared to the Ak 5, well balanced, easy to shoot, and has overall good ergonomics, which was a primary goal of the rifle according to FMV.
