Maybe so. There were a decent number of Mosins that were made by US factories that were sold off by the CMP between the wars.
Both Remington and New England Westinghouse made hundreds of thousands of them for the Tsar in WW1, very few were delivered. After the war DCM (the ancestor of CMP) sold them to the public for pennies on the dollar. US ammo makers loaded 7.62x54R for them until the late '40s.
The first imported Mosins, if I recall correctly, were Finnish, which generally have much better, ugh, pardon the pun, finish, than Russian ones. They started to come over in the 60s.
The Finns couldn't afford to design a new rifle so they standardized on the Moisin, which they had plenty of. They never made thier own receivers....they would take captured Russian Mosins apart and build new rifles around the receiver. Fit and finish is definitely better, and they tend to be considerably more accurate...especially the M28 and M28/30 rifles made for the SY (Civil Guard). If you want a Mosin that will astound you, get a 28/30. The Finnish rifles are a lot rarer than the Russian imports coming in now.
Those rifles, if they were imported in the FO world would not have had the "communist" stigma one them. It's only recently that massive ammounts of soviet rifles and carbines have made their way over. They're so abundant, you can pick one up for about $100.
-Gunny out.
The avalanche started when the USSR went belly up. The Democrats banned all the best stuff, like Makarovs and Dragunovs. There are also some neet items, like the 7.62x54R Winchester 95s military muskets made for the Tsar in WW1 that will probably never be imported because the Russians are asking too much for them.
