WE M4 300-Round AEG Hi-Cap Metal Magazine (Black) | Airsoft
The WE-Tech 300-Round High-Capacity Metal Magazine for M4 / M16 Series AEGs (Black) is built for durability, sustained firepower, and reliable feeding performance. Constructed with a heavy-duty stamped metal outer shell, this magazine delivers a realistic weight and appearance while standing up to intense skirmishes.

Frequently Asked Questions
What is the magazine capacity?
The magazine holds approximately 300 rounds. Actual loading can vary slightly with BB size and loading technique — a speed loader makes topping up faster and helps avoid feed-lip damage.
What firing modes does it have?
It offers semi-automatic and full-automatic fire with a safety position on the selector. Use full auto in short bursts — it empties the magazine and drains gas or battery noticeably faster than semi.
Is it full metal?
Yes — the main external construction is full metal, which gives it a solid, realistic weight. Metal parts still need normal care: keep moving surfaces clean and lightly lubricated.
What BBs does it use?
Standard 6mm airsoft BBs. Use 0.20g BBs for chrono and general play; 0.25g BBs fly steadier outdoors. Choose polished, seamless BBs to protect the inner barrel and hop-up, and never reuse fired BBs.
What warranty and shipping cover this item?
It is covered by the Airgrix 30-day limited warranty and ships from our California warehouse. It counts toward the $59 free-US-shipping threshold. Returns are handled under the store returns policy — see our Ordering, Shipping & Warranty FAQ page for the details.
