Atlas Custom Works Electric Winding 1500Rd High Capacity Box Magazine for M249 AEGs, Woodland Camo

The M249 platform demands a magazine that can keep up. Traditional box mags require a hand crank between reloads, and hi-caps that rattle and need winding mid-skirmish break your rhythm. This Atlas Custom Works electric box magazine solves both problems with a motorized feed system that delivers 1500 rounds without ever touching a crank handle.

Electric winding, no manual cranking. The built-in motor feeds BBs from the 1500-round reservoir with the push of a button. A pressure switch is included for hands-free operation—mount it where you can tap it with your thumb or trigger hand. The charging cable is in the box, so you can power the feed mechanism without hunting for accessories. Just note that the battery itself is not included, so budget a compatible pack for sustained use.

M249 ecosystem, not universal. Unlike M4 magazines that swap between brands, M249 box mags are platform-specific. This one fits Atlas Custom Works and Classic Army M249 AEGs, plus other M249-pattern rifles. If you're running a different M249 variant, verify the feed lip geometry before ordering. Spares for this platform are harder to find than M4 mags, so treating this as your primary support gun means planning ahead.

Woodland Camo finish. The woodland camouflage pattern matches typical M249 loadouts and blends into outdoor environments. It's a cosmetic choice that keeps your support rig looking cohesive without standing out on the field.

What this is for. This is a support gun magazine. You're running sustained fire from a fixed position, covering advances, or playing a milsim role that demands high capacity. It's not for run-and-gun CQB where weight and bulk slow you down. The 1500-round capacity means fewer reloads, but the box form factor adds length and weight compared to a standard mid-cap.

Includes the magazine, pressure switch, and charging cable. Battery not included.
