I lost my cil 300 mag years ago so I purchased one more and left it at home. .I had some clips from a marlin 2lr xt,after a bit of filing till it fit snug,i used 3 of them for a few years.Plus if I lost one ,it was nothing to replace.
Then when I sold the rifle I had the right clip in mint shape to seal the deal. Plus I added in the xt clips,no compliant ever from the guy.
Took me 20 minutes of tinkering and filing and slick as that.The 300 and 520 might be very close if I remember correctly so if they are you could give this a try.
