Furnature is a slang term to describe the fittings on a rifle, namely the heat cowl, foregrip and stock. It originated from the fact that older military rifles (M1A1, Mosin Nagant, Krag etc), and even some modern rifles, are outfitted with wooden foregrips and stocks.

Modern rifles may be described as having 'polycarbonate furnature', or 'laminate furnature' etc as materials have progressed.
