The XM8 WAS discarded, however (Most likely financial reasons), and was never put into service by anyone.

And before you (anon) ask...

1. Video Games are very rarely accurate, assuming there are any accurate games.

2. Put into service means widespread use, like the M1 Garand in WWII, the M14 in the Vietnam War, and the M16A4 today, not testing it.
