If it is considered that only a total of 19.072 were produced (starting 1947) in Argentina , you may or may not find the traces of difficulties in every start of a production line.

As a consequence of that relatively low number is that there is not such a widespread experience with these actions.

The specimen I could inspect showed a lower quality of finish and the sign of intensive use.

So I would hesitate to invest a lot of money in a rifle project on that base.

That will not say that I can judge f.e. the quality of steel. Maybe better, equal or worser than the DWM manufactured 1909
