WE Tech M4 Open Bolt Airsoft Rifle Drum Magazine 350 Rounds - Green
Looking to turn your GBB M4 into a real BB-slinging monster? The WE Tech M4 Open Bolt Drum Magazine is all about serious firepower and no-nonsense reliability. With a whopping 350-round capacity and a gas reservoir built to keep up, this drum mag is the perfect match for any green gas-powered open bolt M4 or compatible GBB rifle. Built from tough injection-moulded polymer, it's lightweight enough to keep your loadout mobile but durable enough to handle field abuse. The winding mechanism on the front makes loading and feeding a breeze, and the easy-fill BB hatch (clearly marked “OPEN”) adds to the user-friendly design. Inside, it’s powered by green gas, but if you’re looking to mod your loadout for HPA, the bottom-mounted fill valve makes conversions straightforward (though keep in mind—modding voids the warranty). Whether you're laying down heavy suppressive fire or just want to reload way less often, this drum mag brings the fun and the functionality in one tactical green package.
