A smarter MWS magazine

The Guns Modify EVO MWS M4 magazine is a clever take on the gas magazine for Tokyo Marui and Guns Modify MWS platforms. Its core and case design lets you slide the internal core out of the shell simply by opening the butt plate and pressing the release button, making reloads quicker and easier in the middle of a game.

Built to last

A durable polymer shell wraps metal internals and a high-tension spring for reliable feeding of 6mm BBs at a 35 round capacity. A functional thermometer sticker on the core reads the magazine temperature in Celsius, so you can confirm it is in the sweet spot before you commit to a firefight.

V4 blank version

This is the V4 blank version with no external markings, a popular choice for custom and themed builds. It ships with two spare O-rings to keep the gas seal tight over the long term. Browse more airsoft accessories to complete your loadout.

Tips for reliability

Spray a little silicone oil on the core so it slides freely, remove the thermometer protection film before first use, and keep it topped up with quality green gas. Avoid releasing the follower on an empty magazine after closing it.

Frequently asked questions

Which rifles does this magazine fit?

It is designed for the Tokyo Marui MWS system and Guns Modify MWS gas blowback rifles. It is not compatible with other magazine platforms, so check your rifle uses the MWS system first.

What gas should I use?

The magazine runs on green gas or top gas. Keep the magazine and gas at a sensible temperature, and use the built-in thermometer sticker to check it is in the optimal range before play.

Why does the core feel stiff?

The slide-out core is quite tight out of the box by design. Guns Modify recommend adding a little silicone oil to the exterior of the core so it slides more easily during reloads.

Do I need to be over 18 to buy this?

No. This is a spare magazine rather than a complete airsoft gun, so it is not age-restricted in the same way. It is sold as an accessory for existing MWS rifle owners.

What comes in the box?

You get one V4 blank version 35 round MWS magazine plus two spare O-rings to help maintain a reliable gas seal over time. A speed loader is recommended for filling.
