Rheinmetall Defence are developing a new 7.62mm medium machine gun called the RMG 7.62 which takes a unique approach to dealing with heat, the age-old machine gun nemesis.At first glance it looks like a small version of the M134 Minigun, but the RMG is no Minigun.Unlike the Minigun, with its insane rate of fire, the RMG is designed to fire at the relatively slow pace of 800 rounds per minute (the exact rate of fire is user adjustable).
