Forgive my opinion but I think it is in the 2x4 style.

Slight hogs back but with pancake cheek piece is OK but from there forward it looks horrendous.
The receiver inletting doesn't look right to me. I'm accustomed to seeing some wood webbing between the trigger area and magazine area.

My opinion of this stock doesn't count though. Only the owners opinion counts. If he is happy with the stock that is all that matters.
