Serious capacity for MP5 skirmishers

This Well hi-cap dual magazine gives your MP5 series AEG a commanding 400 round reserve. The twin-body design fuses two magazine shells into a single unit, so you carry more ammo, reload less, and keep the classic submachine gun silhouette players love.

Realistic looks, practical feeding

Dummy 9mm rounds along the exterior add convincing realism, while all your BBs feed from the internal reservoir. A winding wheel on the base tensions the feed so rounds cycle reliably into your gun. Simply top up the wind as your shot count drops.

Built for the field

The tough polymer construction is made to survive the drops, dust and knocks of a skirmish day. It seats into the magwell as one solid unit for fast, fumble-free handling under pressure, and the generous capacity makes it a favourite for suppressing fire and defensive play.

Check your fitment

This magazine is designed for Well MP5 replicas and typically fits other TM-pattern MP5 series AEGs, though magwell tolerances differ between brands. Stock up on ammo and gas in our BBs, gas and batteries range, or browse more airsoft accessories.

Frequently asked questions

How many BBs does this magazine hold?

It is a hi-cap holding around 400 rounds across the twin-body design, so you can play longer between top-ups.

Which guns will this fit?

It is made for Well MP5 replica AEGs and generally fits other TM-pattern MP5 series AEGs. Magwell tolerances vary between brands, so occasionally a snug or loose fit is possible.

How do I load and feed it?

Fill the reservoir with 6 mm BBs, then turn the winding wheel on the base to feed rounds up ready to fire. Re-wind as the count runs down.

Do the external rounds actually fire?

No. The visible cartridges are cosmetic dummy rounds that add realism. All BBs feed internally from the reservoir.

Is it one magazine or two?

It is a single dual-body unit, effectively two magazine bodies joined together for a bigger reservoir and a realistic look, inserted as one piece.
