Bullgear 2500 Round Box Magazine Kit for A&K M249 Airsoft AEG Machine Gun (ATACS-FG)

If you run a support role on the field, your box magazine is the lifeline that keeps your squad moving forward. The Bullgear 2500 Round Box Magazine Kit for A&K M249 Airsoft AEGs is a serious upgrade designed for players who demand flawless feeding, durability, and battlefield reliability. With an enhanced feeding system, rugged construction, and seamless integration into your M249, this box mag ensures you can unleash steady streams of BBs without the frustration of misfeeds or constant reloading.

Built for Durability and Realism

The Bullgear M249 box magazine is engineered with a durable polymer shell wrapped in a nylon cover, providing both strength and field authenticity. Inside, the feeding mechanism is constructed from solid aluminum, a huge step up from standard plastic internals found in stock magazines. This makes it far more resistant to wear and stress, even under heavy sustained fire.

Bullgear’s attention to detail doesn’t stop there—the internal aluminum gears and reinforced design help this box mag outlast and outperform standard options. Whether you’re laying down suppressive fire in a milsim event or dominating weekend skirmishes, this kit is designed to withstand the abuse that comes with the support gunner role.

Smarter Feeding System – No Extra Wires, No Hassle

Traditional electric box mags often rely on separate wires, hoses, and even dedicated batteries, which can add unnecessary complexity and failure points. Bullgear solved this by creating a simplified automatic feeding mechanism that pulls power directly from your gun’s main battery. That means no extra batteries, no clutter, and no mid-game hassles.

The upgraded motor strength ensures consistent feeding even under high rates of fire, with an adjustable feed rate of up to 2400 rounds per minute when running an 11.1v LiPo. This guarantees that your M249 stays fully supplied with BBs, keeping up with even the fastest trigger pulls and most demanding firefights.

Fast Reloads – More Time Shooting, Less Time Fumbling

With a massive 2500 round capacity, this box magazine allows you to stay in the fight longer without worrying about constant reloads. The improved design makes reloading smoother and faster, so you can top off and get back in action with minimal downtime. For support gunners, every second counts—and Bullgear built this system to maximize efficiency.
