Based on this chart it appears to have better dps than the Sturmgewehr 44 both close and far as well.
No way. The calculations from OP may be correct for rifles, but the dps calculation of machine guns works entirely different. Also, he does not include cooldown modifiers for different weapon ranges. So the calculation is pretty much useless for comparing assault rifles with normal rifles^^
Assault rifles/machine guns deal multiple times the damage from any rifle.
