4 aluminum and 1 steel H&K G3 (HK91) 7.62x51 mm German mags. Will also fit CETME rifles. Not super valuable, Google search to find out what they're going for nowadays. The steel mag will fetch a little more than the aluminum ones. They used to be dirt cheap (like 99 cents a piece) back in the early 2000's.

Thank you. I knew I had seen them before. But I just couldn’t recall where it was.
