AK47 magazines are available in steel and polymer types, each with varying advantages and disadvantages. Polymer AK47 mags are much lighter than steel, are more flexible, and can also be textured for enhanced gripping. Polymer magazines are also (generally) cheaper than steel mags, and owners won't have to worry about rust issues. Steel AK47 magazines are much stronger than polymer mags, and owners won't need to worry about their feed lips breaking if dropped, especially when loaded. Most AK47 steel magazines are well-built and will last as long as owners don't let them rust. However, one disadvantage of steel mags is the added weight. Six fully loaded steel AK47 magazines can be quite heavy for 30-round mags.
