If it were the L579 round top action (the later browning safari), I’d go S&K hands down, based on looks frankly.
If it’s the traditional Sako dovetail rail, then you face the usual sako dilemma: factory lows (modern, 2-piece lows for a 50mm though barrel contour could influence), older vintage factory sako mounts probably mediums, conetrols, leupold, or the S&K. Check on whether the S&K for that action is the tap on (like control) vs clamps, i don’t know first hand. On the little vixen action, they are a tap on jam-fit, which on a .222 i think is fine, but.
Personally... been down this road many times, flip a coin: leupold for simple and stout but not elegant, vs. S&K. S&K in a heart beat if they clamp on.
