Here we go again with me having more airsoft problems, So I recently traded my Scar-L for an A&K M249 which works amazingly, at least when the box mag feeds it all the way. The box mag is also made by A&K and was never used before I got it. The m249 works fine with M4 mags but the box mag just does not work. I've looked online for a replacement but since I don't really want to pay $80or more for a new one I'm going to have to find some way to fix the magazine... Anyone know any fixes?
