Magazines get dropped. They get dropped onto concrete, trodden on, and jammed into pouches that are slightly too small, and polymer feed lips eventually give up under that treatment. A metal-bodied magazine simply does not care.
Three hundred and seventy rounds is a practical hi-cap capacity — enough that reloading is occasional rather than constant, without the bulk of a drum. The wind-up mechanism keeps BBs under spring tension so feeding stays consistent.
Standard M4 fitment, so it drops into essentially any AR-platform AEG.

Good to know before you buy
Metal magazines are heavier than polymer, which is the trade for durability — noticeable if you carry four or five. Hi-caps rattle when not fully wound, so top up between engagements if you want to move quietly.
Frequently asked questions
Why metal over polymer?
Durability. Polymer feed lips crack under repeated impact; a metal body shrugs it off. The cost is weight.
Will it fit my rifle?
Standard M4 fitment, so it works in the great majority of AR-platform AEGs.
Does it need winding?
Yes. Give the wheel a few turns before you head out, and add a few more whenever there is a lull.
Should I run hi-caps or mid-caps?
Hi-caps mean fewer reloads; mid-caps are quieter and force a more realistic reload rhythm. Plenty of players carry both.
