310-Round KS-90 mid-cap magazine made out of durable ABS composite. Compatible with Echo 1, JG, KS, AGM, Tokyo Marui and CA KS-90 full metal gearbox AEGs. Good quality, fit and finish.
This magazine may be confusing to load for first-time KS-90 / P90 hi-cap magazine users, so here are step-by-step instructions:
1. Locate the trap door on the top side of the magazine and fill to capacity with precision high density 0.20g or heavier BBs.
2. Once BBs are loaded, proceed to wind the gear/wheel on the opposite side of the magazine, just as you would a standard hi-cap mag.
3. Wind for about 4-8 seconds, or until you begin feeling a slight resistance against the gear, at which point you may stop winding.
4. Place the magazine on top of the rifle receiver, locking it securely into place, and begin firing. Magazine will need to be rewound as you shoot.
