Bidyanus. I am sure that many rifle stock makers in Australia will be able to have made-to-measure full stocks made for your Sakos and I leave it to the Forum's Australian members to point you in the right direction. For the nose caps, Recknagel in Germany produces them in two different sizes, see http://www.recknagel.de/Joomla/images/stories/Downloads/Recknagel-Zubehoer_8-Katalog_1_Korrektur.pdf page 26, items 28000-0145 and 28000-0155. You will also see in this catalog many different items such as steel butt plates, swing swivels, etc. that might be useful for your project. Regards. Louis
