The pdf of the article is out there somewhere. It was from a police magazine I believe. They also tested Steyr Maadi AKs and Galil 5.56s that likewise choked. I know they ultimately settled on a Galil for cost but the Valmet survived all as it was built and improved over the AK.
It even listed how they died. Most just froze but the G3 cocking handle either froze shut or became brittle.
To be fair, arctic AR care has come a long way but Finland knows the cold.
IIRC the Galil mags were the main failing point. Again, someone should truffle that article
