The Heckler & Koch MG4 is a full-size airsoft light machine gun engineered to deliver sustained firepower for players who need reliability, capacity, and battlefield presence. Modeled closely after the real MG4 used by modern military forces, this electric AEG version maintains the imposing silhouette and rugged build while staying under the legal <1.0 J energy limit for safe recreational use.

Constructed with a high-quality aluminum housing, the MG4 offers durability and structural rigidity that feels solid during operation. Despite its full-metal construction, the rifle maintains a manageable weight of 4200 g, allowing players to handle long engagements without excessive fatigue. The system is powered by LiPo batteries, stored inside the folding stock, ensuring consistent output and reliable cycling during continuous fire.

True to its role as a machine gun, the MG4 features an exceptional ammunition capacity. The standard magazine holds 900 rounds, while the external ammunition box boosts total capacity to 4000 rounds, enabling prolonged suppressive fire without frequent reloads. The firing mechanism operates exclusively in full-auto mode, supporting an impressive rate of fire of approximately 1,000 rounds per minute, ideal for covering fire and area control.

The rifle includes an adjustable hop-up, allowing players to fine-tune trajectory and accuracy when using the recommended 0.20 g BBs. Additional enhancements include a metal bipod for stable firing positions, a foldable carry handle, a robust cocking lever, and an ambidextrous safety lever for user-friendly handling.

Measuring 1030 mm, the MG4 provides a long sight radius that improves tracking and target alignment. Its Picatinny mounting rail allows the use of optics or the included flip-up sight, giving players flexibility across different field environments.

With its realistic handling, massive magazine capacity, and reliable AEG internals, the MG4 stands out as a top-tier support weapon for players seeking a dominant presence on the field.
