I picked up my new Yugo M70AB Underfolder. Looks good. The problem is that I cannot seat all of my mags in it. Some just quite simply do not make it far enough to the catch. Some, however, do just fine, but fight so tightly that removing them requires a good squeeze of the hand. I'm guessing the magwell wasn't cut to allow any extra space. In comparison, all of my mags (Romy, Hungarian, Pronag, AND Tapco) all worked in my converted Saiga. Any idea as to what may be the problem and if it is easily fixed? There is no correlation between mag type either; it works on some Hungarians, Romy's etc. then not on others of the same type.
