Half track rear floor question?

[dfanders]

Gents,

Here are pics of what appears to be a half track rear floor front half. I think it from a M16 50 cal quad mount version. Any other ideas?

Yes that looks like part of an M16/M16A1 floor.

It looks like the rear half. The box on the bottom side is located in front of the rear x member.
