Integrated battery bag within 3-point tactical sling uses hi-grade high-flow silicone wires that allow you to power your AEG with a large battery strapped obliviously to your sling. Carefully engineered so that the battery's weight does not affect the balance of the sling. In fact, the battery is positioned to lie against your lower back so that you do not feel it on you at all. Perfect solution to powering highly upgraded but compact AEGs that have either no room to store a large 8.4v or 9.6v battery, or that storing the battery with the gun would ruin the realistic look of your beloved rifle! Quick release mounts allow fast and easy attachment. Includes a fixed stock harness for stylish and comfortable attachment to rear stocks without a hook type sling mount. Tested and recommended by airsoft players! (Pictured G36C & Battery are not included).
