I have an action cover with a scope attached sitting in a parts bin somewhere in my shop. It came with a bunch of AG42b parts I received a few years ago. I can take some pictures if anyone is interested?
The problem with scoping the AG42 is that you need to put your hand on top of the dust cover and grasp both of the projecting nubs to #### it. A side mounted scope prevents this so you would need to attach a cocking handle that would clear the scope mount.
7.62x39 sounds more interesting than 7.62x51.
Why would the Swedes want to convert to 7.62x51 mm? The 6.5x55 mm is a great cartridge, the Swedes must have had vast quantities in the supply chain - this cartridge has been around since the turn of the century. And why would anyone go to the trouble of converting a AG42 to .308? Just to do it? What would be the gain? the 6.5x55 mm is fine for hunting and the AG 42 is not really. Its long and frick'n heavy. Can someone please explain?
I had no problem with my scope mount and it bridged both sides. All you need is to move the two operating knobs rearward enough it releases the slide. The scope mount just has to be rearward of these knobs that are near the front of the cover. It does work and is functional.
