Why we like these:
Esstac KYWIs are by far our favorite magazine pouches. The combination of a kydex wedge and a nylon pouch is so simple yet works so well.
Since this is the 'shorty,' this is a great extra rifle mag pouch for a shooting belt. But you can also attach it anywhere on your kit you have molle and want a spare mag.
Official description from Esstac:
This pouch is made for STANAG magazines. "AR15 style magazines".
**AK magazines will NOT work in this pouch.**
With A straight forward, user friendly and highly intuitive design the single KYWI mag pouch is like no other. Utilizing a hybrid kydex and nylon design ,you get all the rigidity you would expect from a kydex pouch and the lack of noise you want from a nylon pouch. These pouches feature our kydex wedge insert (KYWI) that provide the needed retention to secure your magazines without the need for bungee cord for rapid mag changes.
