Vince,
That gotta be a Richards Tactical Stock, like the brown/almond one you have. It looks just like it, only without the vents cut into the forend and looks like the bottom has been sanded down to be more smooth. That is my guess.

Heres a pic of my old Richards Tactical to compare the resemblance:
