The Auto-Winding Drum Magazine 2300bb for M4/AR15 produced by G&G Armament is the ultimate support fire solution. Made from ultra-light black polymer (weighing only 612 grams), it offers an impressive 2300 BB capacity. Its true strength is the hybrid system with 3-position switch: you can choose to use the electric winding in Automatic mode or Manual mode (thanks to the motor powered by a 7.4V LiPo battery included), or put it on Off and rely on the large front-loading wheel for manual loading in case of emergency! Maximum tactical versatility to never stop your burst. Compatible with G&G M4 and standard STANAG replicas.

Tactical Design and High-Tech Polymer:
G&G has taken the design of its famous manual drum magazines and evolved it to the maximum. The exterior is made of the same high-density polymer that ensures impact resistance while keeping the empty weight at just 612 grams. This allows you to transform your M4 into a SAW (Squad Automatic Weapon) without finding yourself with a forward-biased rifle that's hard to handle.
Complete Control: 3-Position Switch and Manual Wheel:
The internal reservoir holds 2300 BBs, but it's the electronics that make the difference. The system is powered by a powerful 7.4V LiPo battery (included with Mini Tamiya connector). The control is achieved through a clever 3-position switch:
1) Auto: the motor winds the spring in complete autonomy to guarantee uninterrupted suppressive fire.
2) Manual (Electric): the motor only activates when you press the button, giving you control over the noise.
3) Off: turns off the circuit. And here comes the true "Plan B" of G&G: the large front-loading wheel. With the circuit off or the battery discharged, you'll just need to turn the wheel by hand like a classic hop-up to continue firing!
How to use the 3-Position Switch: This switch is your best tactical ally! Use the AUTO mode when your team is under enemy fire and you need to return fire without thinking about anything else. Use the MANUAL (Button) mode for standard patrol phases. And if you're sneaking around the enemy undetected? Put the switch on OFF and load the spring by turning the large front-loading wheel by hand: zero electric noise, 100% surprise effect!
LiPo Battery Management: Be careful, the motor is powered by a Lithium-Polymer (LiPo) battery! This ensures excellent performance, but requires care. Use only balanced LiPo chargers (connect them to the included charging cable). Never let the battery discharge to zero, or it will swell and stop working. At the end of the game, always disconnect it from the magazine.
Rest and Maintenance: In addition to the battery cables, remember the mechanical parts. At the end of the day, remove all BBs from the reservoir and let the large internal spring discharge completely by pressing the upper blocking tooth. If you leave it engaged, the motor (and your hand) will struggle to recharge it the next Sunday.
