When it comes to staying in the fight, capacity and reliability are everything. The Matrix Metal 300rd Hi-Cap Magazine for M4/M16 Series Airsoft AEG Rifles (Black) delivers both — combining rugged metal construction, smooth feeding performance, and a generous 300-round capacity to keep you firing longer and reloading less.

Designed for compatibility, strength, and authenticity, this hi-cap magazine is the ideal choice for any Airsoft player looking to upgrade their loadout with a dependable and realistic feeding solution.

Realistic Metal Construction

One of the defining features of this magazine is its stamped metal outer shell, engineered to replicate the look and feel of real AR-style magazines. The metal body doesn’t just enhance realism — it adds extra durability to withstand the rigors of field use, whether you’re running a milsim loadout or competitive skirmish setup.

The matte black finish complements any rifle, offering a sleek, professional aesthetic that matches both classic M4s and modernized AEG platforms. From its texture to its weight, the Matrix 300rd Hi-Cap feels just right in the hand and performs even better under pressure.

High-Capacity Feeding System

Inside, this magazine houses a high-capacity winding mechanism that holds up to 300 rounds of 6mm BBs — enough to keep you in the action through extended firefights. Simply open the trapdoor on top, pour in your BBs, and use the easy-access winding wheel at the base to load tension into the spring feeder.

The smooth internal design and precision-fit feed channel ensure consistent feeding with minimal jams or misfires, even during full-auto bursts. Whether you’re using a Matrix, G&G, Krytac, or Tokyo Marui AEG, this mag keeps your shots flowing smoothly with every trigger pull.

Universal Compatibility Across Major Brands

Matrix engineered this magazine with universal compatibility in mind. It’s been tested and verified to fit and feed flawlessly with a wide range of popular M4/M16 platform AEGs, including:

• Matrix, WE, G&P, APS, S&T, Tokyo Marui, G&G, Krytac, ICS, VFC, SRC, King Arms, ARES, Amoeba, KWA, JG, Dboy, CYMA, A&K, Echo1, and Classic Army models.

This wide compatibility means you can swap between rifles without worrying about fitment issues, making it an excellent choice for players who own multiple AEGs or frequently change setups.

Durable Polymer Internals and Smooth Operation

While the exterior is built from steel, the internal components are made from high-quality injection-molded polymer, balancing strength with lightweight performance. The polymer internals help reduce friction, ensuring that the BBs cycle efficiently through the feeding channel and into your rifle’s hop-up unit.

Combined with the rugged metal shell, this hybrid construction provides the perfect balance between longevity, reliability, and handling comfort — ideal for both casual players and seasoned Airsoft enthusiasts.

Easy to Use, Battle-Ready Design

Reloading and winding are simple, fast, and field-friendly. The bottom winding wheel allows players to easily maintain spring tension during gameplay without disassembling the magazine. This ensures your BBs are always ready to feed on-demand — no downtime, no fumbling, just performance when you need it most.

The magazine’s compact, ergonomic design fits standard M4/M16 magwells and most MOLLE-compatible magazine pouches, making it a seamless addition to any tactical loadout.
