Dalkowski-
My understanding of these conversions is that they stem from the Treaty of Versailles? Are these not German military firearms that were de-militarized by the conversion into something that could still be used under the treaty's supervision?
Additionally, the metal in the action is exceedingly thin to allow for the 12ga barrel, and the locking lugs of the bolts are barely engaging on them.
As I understand this to be true,(at least in the case of the ones I've been shown) Please tell us their origins, and what weaknesses we might encounter that would cause us to lose an eye.
I would not buy or sell one of these, knowing they could easily chamber a deadly load through operator error.

Out there doing it best I can.
