These are generally considered the most desirable metric magazines. There are a couple of follower design variations, and several generational differences in anodizing methods. Like most anodized gun parts, these magazines show wear very quickly. However, they are the lightest-weight FAL magazines available. Argentine and Brazilian metric magazines look just like Belgian magazines, except that they have zinc phosphate coated followers.
Zinc phosphate is a type of phosphate that is usually gray.
Manganese Phosphate is usually black. Austrian metric magazines are entirely zinc phosphate coated. They are currently available from D.S. Arms. Israeli magazines are generally found wrapped in brown waxed paper tied up in twine. They are packed either four or five to a bundle.
