The extended magazine upgrade doubles the magazine size from 100 rounds to 200, effectively doubling the amount of 'buzzing' through enemies you can potentially do in one load of ammunition. The MG42 is unlocked after completing the mission Payback, and can be fitted with two attachments. As with its real-world counterpart, the MG42 features a notably high rate of fire, being able to put several hundred rounds down-range in a few moments. The MG42 first appears in Far Cry 4 in Kyrat. A relic from WWII, this German machinegun has such a high-rate of fire that it shreds enemy soldiers and has earned the nickname: Hitler's Buzzsaw.
