The Wes Gear External battery pouch is a great improvement over past designs. In the past battery pouches would often be a hassle, often coming loose due to weak velco straps. However, our new pouches feature 2 fully adjustable 18" straps that can be securely fastened to the stock of your airsoft gun and modified to fit your needs. Although this new pouch replicates the butt stock mag pouches already available, it features a slimmer profile that can hold up to a 12v battery and two elastic bands designed to hold your battery in place. This pouch is a must if you plan to wire your airsoft gun to the back.
This pouch is designed specifically for the M4. Other airsoft guns may require some modification.
