AR Spring for AK Mag

I don't have a cool Russian... I mean Donovian backstory for this one. Made it while bored at work. It'll let you run standard AR15 magazine springs in my AK74 mags or Laff Dynamics proxy mag, I'll try to make one for standard surplus mags and the AK12 clone mags soon. I'm too tired to put a cool pic up too so here's a picture of my recently passed away cat. RIP Kai, you were a real one
