What type of 98 action would be on this Husqvarna FN, 640? I’m asking because to use Leupold bases I had to use a shim under the rear moun to get it level, I’ve run into this before on a 98 Zastava Leupold sent me some shims explaining the 98 action has many variations shims are required on some models.
Another curious item is a third Magpul sling mount just forward of the trigger guard what could it be used for?
