I recently bought (2) Yugo 80% rec. with templates from AKparts.com. everything looks great ,except when I lay a tapco flat on the template,lining up the front and mag well...Nothing else lines up. some of the holes are way off. I just thought that I would check it with a flat before I actually cut it, I'm glad I did. anyone else ever had this problem? should I just take my measurments off the flat ?
