G&G has created one of the most innovative and futuristic magazines for M4/M16 users who are looking for the best gameplay experience available. This drum style magazine holds 2,300 rounds of 6mm BBs, letting players provide cover fire throughout the battle and take the win. G&G offers two versions of this drum magazine, based on player preference and availability. This specific version utilizes an included 7.4v 800mAh battery to operate the internal motor that automatically winds the wheel, feeding BBs into the high tension spring. An on/off switch located at the rear of the magazine quickly starts or stops the feeding process, providing faster reload time than having to manually wind the wheel every reload. The storage chamber is filled from the door on the back of the magazine and has an enlarged opening to pour BBs into the magazine directly from a bottle or bag. A high quality polymer was used for the construction of this magazine to provide a lightweight yet durable build, even when completely full. The universal design of this magazine allows it to be used on all M4/M16 style rifles. Run onto the battlefield confident you have what it takes to take down anyone standing in your way of victory.
