The Automatkarbin 5 is based upon the FN Herstal FNC, which was developed for NATO trials. It wasn't accepted but made a return a few years later in the Swedish army. We have thereafter had Bofors, currently BAE Systems, improve on it to fit the specifications of the Swedish Military. It fires standardised 5.56 NATO rounds in a 30-rnd magazine.
Its predecessor, the AK4, fired 7.62 NATO and was based upon the German HK G3.
tl;dr: It ain't Russian Xact. and you will not find Russian ammunition that much in Sweden. If you are looking to resupply you will have to go for NATO rounds, as they are used in private hunting (same caliber) and the military.
