Excellent pouch. Have 2 on my carrier. I use one for a 20 rds of TAP Barrier and the other has 3 SWAT tourniquets in it. Will hold a 30 rds mag no problem. My duty plate carrier is 90% ATS components. There's a reason for that.
Short-Single M4 Magazine Pouch
Our Short-Single M4 Magazine Pouch is designed to securely hold one twenty or thirty round M4 style magazine, and works well as a "fast mag" pouch on your first line. Our pouch features an open top that has an adjustable bungee retention cord around the body of the pouch. Bungee tension is adjustable using an ITW/Nexus Toaster Cord Lock.
The pouch has additional 1" webbing on the front of the pouch allowing you to layer small MOLLE compatible pouches, such as a single pistol magazine or multitool pouch, on the face of the Short-Single Shingle. This pouch is constructed from 500 denier abrasion and water-resistant Cordura nylon and it attaches to any MOLLE/PALS modular webbing. M4 magazine pictured is not included. Lifetime warranted against defects in manufacturing workmanship and materials. Like all ATS made gear this pouch is made in the US of A of the the finest quality components.
