The 5.56 double stack kywi pouch has a elastic loop that sits in the back for the back magazine to slide into. The elastic is there to hold the rear magazine after you pull the front magazine out so it does not fall out.This pouch is made for AR-15 style magazines.
**AK magazines will NOT work in this pouch.**
Add WTFix straps or Belt Loops?
