finish. Over time, most first production m/45's were converted by permanently riveting the magazine support to the receiver. UN/ONU and Ceremonial: the m/45C is an m/45B with a bayonet mount on the barrel sleeve which was used for parade and guard duties. During the Congo Crisis in the 1960s, the Swedish UN forces used the C version extensively. The standard m/45 and m/45B have no bayonet mount. Police: The Swedish Police used the m/45 as a reinforcement weapon, issued to specially trained police officers under exceptional circumstances like terrorist attacks and armed robberies. Unlike the military model it was equipped with a selector switch for full auto or semi-auto fire. The police model designation was m/45BE (E = enkelskott/single-shot) and BET (T = tårgas/tear gas). The BET model was later locked to semi-auto with a screw to the selector switch. The Police model had an all black finish, this in contrast to the slate grey phosphate and enamel green of the military versions. In the mid to late 70's the BE version was retrofitted with a modified stock (m/75) with a removable upper cheekpiece allowing the operator to wear a visored riot protection helmet (Huvudskydd m/69). The BET model was only used to fire a tear gas canister (Tårgaskastspray m/74). To be able to fire the canister, a special blank cartridge (9mm lös ptr m/T) had to be used. A red sticker on the left side of the weapon reminded the operator that only blank ammunition could be used. The BET also had a high front sight and an adjustable rear sight (30, 45 and 60 meters). The m/45 BET was replaced by Heckler & Koch MZP-1 (HP 40) in the early/mid 1990s because it was regarded unfashionable and also because new tear gas canisters became hard to obtain since they contained the hazardous substance: Freon-12. Manufacture and use The Swedish Army list price of the Carl Gustaf m/45 in the late 1970s was around 600 Swedish krona. The Carl Gustaf m/45 was replaced in the Swedish Armed Forces during the mid-1960s with the 7.62mm Ak 4 battle rifle, and starting in 1986 with the 5.56mm Ak 5 assault rifle. On 2 April 2007 the kpist m/45 was officially declared obsolete when it was retired from the Home Guard who were the last users in the Swedish Armed Forces. In addition to Sweden, several other countries have used the weapon,
