Hi-cap means wind-up: how this magazine works
A hi-cap (high-capacity) magazine holds up to 400 BBs loose inside. A spring that you wind by hand pushes them up to the gun. Because the BBs sit loose inside, a hi-cap rattles when you move.
- Fill. Open the fill door on top of the magazine and pour in BBs.
- Wind. Turn the winding wheel on the bottom until the clicks get firm. Stop there.
- Play. Insert the magazine and play. When the gun fires but no BBs come out, wind it again.

Don’t want to wind? Choose a mid-cap instead: the KWA MS120 AEG Mid-Cap Magazine, 3-Pack, the KWA MS120c Adjustable Mid-Cap Magazine, 3-Pack, or the MS120 in Ice, Mint or Midnight.
KWA continues it’s tradition of innovation with the all-new K400 high-cap magazine! You can now carry a nearly unheard of 400 rounds using the same space as any standard AEG magazine, like the legendary K120, so the mags will still fit in any M4 rig or mag pouch without any issues.
