Yes, Virginia, there IS a Gevarm CENTERFIRE...
I'm a BIG fan of the four models of .22rf Gevarm rifles which were intended for export to the North American continent. These four differ from the ones Gevarm made for their European market. I've since learned there exists a Gevarm marked SHORTS, and its owner reports none of the standard 8-rd and 20-rd magazines known here will work in his rifle. And, he says he's run into other people who report they own similar rifles.
Over the years I've run into quite a few Gevarm rifles in centerfire calibers but never paid any attention to them as I had no interest in centerfire. Though I didn't pay much attention to them I noted the sellers always mentioned the high quality of the firearm. DUH? I wouldn't expect less from them...
I can speak for the VERY high quality of their .22rfs only. This posting is simply to verify that, yes, Gevarm made many firearms, both rimfire AND centerfire, which were never offered by importers on this side of he pond. WHY, I cannot answer, but I suspect it was wholsales cost wouldn't let them be competitive with our domestic firearms.
