I approve of this hypothesis. ^^

Anyway, I think AUGs should be fine. It's a good weapon and I can foresee it being used decades into the future. Maybe not the A3 specifically, but an updated version. That said, I'm guessing your character's a marksman, so he'd probably be using the HBAR-T variant of the A3. The 42 round mag is really more for the HBAR version, and an M203 doesn't really fit a marksman character. Maybe give it a bipod and a scope of your choice.
