As far as I know, there aren't any wood furniture sets, regardless of national origin, with bipod cuts. I'm not certain if you could mill out bipod cuts in a wood handguard and keep it strong enough for the job (you could design it properly, but I don't know if it could be done isn't already designed for bipods). You could always go the route of the rifle on the left on the Land Rover and just go wood butt (or wood butt and grip, as on the German G1 and others). That would leave you full use of the bipod.
In any case, you've got a nice-looking rifle.
