I have a bunch of Husqvarnas built on the HVA 1600 series action and have no objective clearance issues with 40mm objectives in low rings Leupold/Redfield turn-in style mounts or with Leupold QRs.
Since the HVA/1600 series hasn't been made since the late-1960's or early-1970's, your options might be limited. My "shooter" Husqvaras in 256 Newton and 338-06 have Weaver bases and Warne rings on them.
Has the stock been shortened on your rifle?
That's good info to know, thanks! I don't think it was shortened but apparently, it is a custom-ordered stock (extra tall comb) made by a stockmaker or gunsmith in Sweden, where supposedly it was a common practice among hunters. Well, this I've been told by a poster on another board, somewhat of an expert it seems. He also clarified it as a model 1640 Std.
My son pointed out that it looked to have had the original comb sawed off and then a splice added with the original put on top. That may be how it's done? There's a nick in the top front edge of the comb where the bolt has struck it upon removal, repeatedly over the past 60 years. I guess it has some history.
