So a few years ago, those awesome Hungarian 20 round steel mags were all around, then they became more scarce because people love them. These are the pouches that hold three of those magazines designed for armored vehicle crewmembers.
Made of heavy (musty) canvas with leather hardware. Some of the leather has a liberal amount of talc powder as a preserving agent, but it usually comes off with water and a rag.
Conditions will vary slightly, but all are basically like the ones in the stock photo. Each has a tool pouch on either side. 30 Round Ar-15 magazines also fit in here quite nicely, so there's that.
These look great, and are built tough! Grab yours, as there weren't a lot of these made.
