This light machine gun is exactly that: extraordinarily lightweight. Coming in at only 11 pounds, it is extremely manageable to carry around and claims to be the world’s lightest machine gun. The Ultimax 100 MK8 fires from a non-reciprocating, open bolt and puts 5.56x45mm NATO down range at a rate of 400-600 rounds per minute with extremely light felt recoil.
