Delta Armory M4 / AR15 DMAG Hi-Cap Magazine

The DMAG winding magazine by Delta Armory is designed for players who want peace of mind on the field without constantly reloading while still relying on smooth and consistent feeding. With a capacity of 300 BBs, it handles long suppressive fire and intense action without unnecessary pauses with a speedloader. Inside, a strong winding spring ensures reliable feeding even with heavier BBs and higher rates of fire, keeping up with more powerful setups. The body is made of durable polymer with textured surface for a secure grip and follows the look of real PMAG magazines, appreciated especially by Mil-Sim players. Another major advantage is broad compatibility, the magazine fits most AEG rifles such as M4, AR15 or HK416. If you are looking for a simple, functional, and affordable magazine for everyday play, DMAG is a safe choice.

FAQ (Frequently Asked Questions from Our Store)

Does it fit every M4?

In most cases yes, although there may be rare exceptions with extremely tight magwells. DMAG is highly universal and works with brands like Specna Arms, CYMA, E&C, or Delta Armory.

Can it handle higher rate of fire with 11.1V battery?

Yes, that is exactly what it is built for. The strong spring and reliable feeding mechanism handle faster setups, making it suitable even for upgraded rifles or HPA builds.

How do I fill the magazine properly?

Hi-Cap magazines are filled from the top by pouring BBs directly into the loading port. Afterwards, wind the wheel on the bottom. Never use a speedloader designed for mid-cap magazines, as it may damage the internal mechanism.

What should I buy with the magazine?

Quality BBs are essential, ideally from brands such as BLS, Specna Arms Ultra, or ASG. Having multiple magazines is also recommended depending on your playstyle.
