These are used 30 round magazines made by FN in Belgium, Post WWII manufacture. AYP marked. Very high quality, heavy-weight magazines match original G.I. Magazine Specifications. They are the later version of the US GI Contract "Split Back" magazines, made from 2 pieces of steel. These are new unissued magazines that have been stored for many years in the original FN factory crates. A small number of these show some surface rust freckling and some show minimal amounts of blueing wear from transportation vibration but are new and guaranteed to feed and function in all G.I. Carbines. These are the best quality 30 round magazines available in the country today.
