The XM913 has been selected as the primary weapon on the US Army's new Next Generation Combat Vehicle, the XM30 MICV.

The projectile itself is 50 mm in diameter, encasing a long thin dart, designed to pierce armored vehicles.

A light "sabot" grips the barrel's rifling, in order for the shell to get the full power of the expanding gas.

Tracer rounds have a button of pyrotechnic chemical that leaves a trail to help a gunner observe the trajectory/path of the shot.
