Atlas Custom Works 360Rd Full Metal SR-25 High Capacity Magazine, Black

Running out of BBs mid-skirmish is a problem with a simple solution. The Atlas Custom Works SR-25 high-capacity magazine holds 360 rounds, which is roughly the equivalent of ten standard mid-cap magazines in a single feed. You wind it once at the start of a game or during a reload, and it delivers round after round without the constant mag-swapping that leaves you exposed.

Full metal construction. Unlike polymer hi-caps that crack after a season of use, this one is built from metal throughout. The body, the feed lips, the winding mechanism — all metal. It adds weight compared to plastic alternatives, but it also survives drops, impacts, and the kind of rough handling that happens when you're moving through tight spaces or crawling over debris.

Platform fit. This magazine is designed for Atlas Custom Works SR-25 AEG rifles and other similar SR-25 platforms. The dimensions and feed geometry match the receiver's mag well, so it seats properly and feeds reliably. If you're running a different SR-25 variant, check the fit before your first game — platform tolerances can vary.

What to expect from a hi-cap. High-capacity magazines use a spring-fed wheel that you rotate to feed BBs into the chamber. They rattle when you move — some players add foam to dampen the sound. They hold more rounds than mid-caps, which means fewer reloads but also more weight. For CQB or short skirmishes, a mid-cap might be more practical. For longer games or situations where you want to minimize reloads, the hi-cap pays for itself.

Includes one 360-round high-capacity magazine in black.
