Bear in mind the foresight either needs soldering on, or a dovetail cutting in it (if there’s enough meat). Also, that the drop (or lack of it) on modern rifles is not iron sight friendly - you’ll be needing to jam your cheek into the stock to be able to look through them. Ok for a coup-de-grace but harder for longer shots.
However, Recknagel have plenty of foresight options, along with weaver mount (ie picatinny) rear sights. Should be quite a few different options for rears actually
