 Gepárd M5 is a bolt-action rifle for military sharpshooters and weighs only 13 kilograms, while the M4 is a semi-automatic anti-materiel rifle.The massive 10-round drum magazine, so characteristic of the M2 and M3, was replaced with a straight box magazine design with a capacity for five rounds.The later M4 and M5 can fire either Russian or NATO 12.7 mm ammunition as the gun barrel is field replaceable.
