I have a Tradex "M69" (they're actually M58 and some have newer M69 stocks). I can tell you that they employ K98 actions and bolts (often mismatched) left behind by the retreating Germans, while the Swedish variants are based on Swedish "Mauser" actions (M96) which are also excellent. Both utilize S&L medium-heavy contour barrels. They also employ different types of diopter sights. Personally, I can't tell the difference of what sights are better. They take some getting used to!
I opted for the large ring K98 action because of their interesting history. You can't go wrong either way.
