XM25 "good enough"

GLs have other advantages

(1) Potential exploitation of Medium-low pressure principle.

I am disappointed. Why did nobody point out that rifle grenades inherently kind of exploit the high-low pressure principle?

@Compost: Why should a salvo of rifle grenades wreck the weapons? The rifle/carbine is largely unaffected by the use of rifle grenades.

UBGLs and MGLs will typically not be together in a small unit. 40 mm medium velocity ammunition also puts a bold question mark behind a platoon ("commando", "light" or "patrol") mortar since it has ~700 m range and enough physical effect to achieve similar psychological effect.
