Its magazines only hold 5 bullets, hindering it greatly at close range.
Because of its low capacity, refilling its magazines is a very inefficient use of civilian bullets. This also makes it inefficient to carry on raids, requiring several Bonjour clips and/or boxes of civilian bullets for longer trips.
The Mosen is one of the only two civilian bolt action rifles currently in the game (the other being the Outfield.)
The Mosen is based off the Russian Mosin Nagant, which was created during the late 1800s to serve the Russian army. It was designed to give the Imperial Russian Troops an upper hand against the Turkish, who were armed with Winchester repeating rifles.
Along with many other weapons, this was renamed. Before the bandwidth crash, it was called the Mosin.
