There probably are very few to none so far as people that know anything about that make of rifle. It appears to be much the same as the Traditions Deer Hunter imported to this country. I don't think many sidelocks are built with the idea of periodic removal of the breech plug in mind. Too many things could go wrong.

Looking at the parts diagram http://ardesa.com/en/uploaded/MANUAL...0percusion.pdf , I see no provision to remove a breech plug.
