The modifications to the basic MG 42 design include an extra heavy bolt (950 g (33.51 oz) vs. the 675 g (23.81 oz) MG 3 bolt) which reduces the cyclic rate of fire to around 850 rounds per minute. The rate of fire can be varied up to cyclic rate of fire of around 1,150 rounds per minute, if necessary, by changing the bolt and return spring.
