Three years ago ITW licensed the Fastmag as well as several other designs from Downeast, developers of the MOLLE frame. The first generation of the Fastmag was placed into limited production and proved very popular. However, it quickly became apparent that there was room to mature the design. Many felt that the original version was too wide as it took up too much real estate on a PALS platform. Additionally, engineers at ITW knew that they could enhance the retention of the magazine. Obviously they hit a home run on that one if this video from our friends at MilSpec Monkey is any indication.
There have been many posts online showing the new Fastmag but no one has shown it alongside the earlier version. These photos give you an idea of the many changes made to improve the product.
