The WE-Tech MSK 300-Round High-Capacity AEG Magazine (Black) is an ergonomic, heavy-duty polymer magazine designed for the WE MSK series, as well as a wide range of standard Tokyo Marui-compatible M4/M16 and AR-15 electric airsoft rifles. Styled with modern ACR/MSK ribbed aesthetics, it combines a tactical look with aggressive non-slip handling.
Featuring an impact-resistant reinforced nylon polymer casing, this 300-round hi-cap magazine houses a smooth internal clockwork mechanism powered by an easy-access bottom winding wheel. The enlarged top loading window allows fast BB top-ups in the field, ensuring maximum reliability and continuous firepower during long 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.
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.
