Cyma Magazine CM098 / 098A / 098B SR25 Hicap 420rds Black

The CYMA Magazine CM098 / 098A / 098B SR25 Hi-Cap 420rds Black is a high-capacity magazine for the CYMA SR25 / AR10 AEG series, including the popular CM.098, CM.098A and CM.098B. With a capacity of no less than 420 BBs, this magazine offers considerably more ammunition than a standard mid-cap and is particularly suitable for longer skirmishes where you want to reload less frequently.

The metal outer casing fits the classic 7.62 / SR25 magazine profile perfectly and gives the magazine a solid appearance. Thanks to the traditional hi-cap feeding system, the BBs are fed from the internal reservoir to the hop-up via a winding mechanism.

420 BB high-cap capaciteit

The magazine has a nominal capacity of 420 6mm BBs.

This makes the CYMA M161 particularly appealing to players who want to keep playing for longer without having to constantly change magazines. Compared with an SR25 mid-cap holding, say, 100 to 150 BBs, a single M161 offers considerably more ammunition.

A hi-cap works differently to a mid-cap. The BBs are mostly loose in an internal reservoir and are fed into the feed channel via a spring mechanism.

That is why the magazine needs to be rewound from time to time whilst in use.

Winding mechanism on the underside

On the underside is the distinctive winding wheel of a traditional high-capacity magazine.

After loading, the wheel is wound up several times until sufficient spring tension has been built up. This pushes the BBs upwards towards the hop-up unit.

During prolonged bursts of fire, the spring tension may decrease. If the replica stops feeding properly whilst there are still BBs in the magazine, simply re-tensioning the spring is often sufficient.

There is no need to turn the winding wheel with excessive force as soon as the spring offers noticeable resistance.

For CYMA CM098, CM098A and CM098B

The CYMA M161 magazine has been developed for the SR25 / AR10 AEG platforms from the CM.098 series.

The available product information explicitly states:

• CYMA CM.098
• CYMA CM.098A
• CYMA CM.098B
• CYMA SR25 AEG series
• AR10 / SR25-platform

The CM.098 itself comes as standard from CYMA with an M161 magazine holding 420 BBs. cymagun.com

This makes this standalone storage unit a logical choice as an additional or replacement storage unit for users of this range.

Not a standard M4 magazine

Although the CYMA CM098 clearly belongs to the AR family in appearance, the SR25 / AR10 platform uses a larger 7.62-style magwell.

A standard M4/AR15 AEG magazine therefore does not fit into these replicas.

Conversely, this SR25 magazine does not fit into a standard M4 AEG either. The magazine is longer and wider and has been specifically designed for the larger SR25 / AR10 platform.

This is an important distinction to bear in mind when ordering spare magazines. The M4 and SR25 may look similar, but their magazines have decided not to use the same size.

Steel warehouse enclosure

The outer casing of the M161 is made of steel.

This gives the magazine a sturdy construction and a classic metal look that goes well with an SR25 or AR10 build.

With a stated weight of approximately 220 grams, the magazine is relatively sturdy without being excessively heavy.

When carrying several magazines in a chest rig or pouch, it is, of course, wise to take the total weight of the loadout into account.

Practical insights

Hi-cap magazines are particularly useful when maximum capacity is more important than realism.

With 420 BBs, you need to reload considerably less often than with a mid-cap. This is a clear advantage for long outdoor skirmishes or for players who don’t want to carry several magazines.

The downside is that BBs can move around freely in the internal magazine and may therefore rattle audibly. For milsim players who want maximum silence and realistic reloads, a mid-cap is often a more attractive option.

A hi-cap magazine also needs to be wound up regularly. If the replica suddenly stops feeding whilst there are still plenty of BBs left, check the winding wheel first before suspecting the hop-up or gearbox.

Charging and using

The magazine is loaded via the loading hatch at the top.

Open the cover and fill the internal reservoir with suitable 6mm airsoft BBs. Then close the cover completely.

Then turn the winding wheel at the bottom several times until sufficient spring tension has been built up.

Next, insert the magazine into the replica and check that it is held securely by the magazine catch.

With a new magazine, it is advisable to fire a few short test rounds first and check the feeding before using it during a full skirmish.

Who is the CYMA SR25 Hi-Cap 420-round magazine suitable for?

The CYMA M161 SR25 Hi-Cap 420rds is particularly suitable for owners of a CYMA CM098, CM098A or CM098B AEG who are looking for an additional high-capacity magazine.

It’s a good choice for long outdoor matches, support-oriented play styles and players who prefer to use a single magazine holding hundreds of BBs rather than carrying several mid-caps.

For milsim players or those who value quiet magazines and more realistic reloads, an SR25 mid-cap might be a better choice.

• Do not turn the winding wheel with excessive force beyond any obvious mechanical resistance.
• First, check the winding tension if the magazine stops feeding whilst there are still BBs in it.
• Do not load the magazine via the feed lips as you would with a mid-cap; use the loading door provided for this purpose.

Does this magazine fit the CYMA CM098A?

Yes. The CM098B is also listed as compatible in the product information.

Is this a hi-cap or mid-cap?
This is a hi-cap magazine.

Does the magazine need to be wound up?
Yes. The magazine has a winding wheel on the underside which is used to wind the internal mainspring.

Does this magazine fit a standard M4 AEG?
No. SR25 / AR10 AEGs use a larger magazine profile than standard M4 / AR15 platforms.

Why doesn’t an M4 magazine fit into an SR25?
An SR25 is based on the larger 7.62 / AR10 platform and therefore uses a wider and longer magazine well.

Is the warehouse made of metal?
Yes. The outer shell is described as a steel warehouse shell.

How much does the storage unit weigh?
The stated weight is approximately 220 grams.

How do I load the magazine?
Open the loading hatch at the top, fill the magazine with 6mm BBs, close the hatch and then wind up the winding wheel at the bottom.

Why does my hi-cap sometimes fail to feed even though there are still BBs in it?
The tension in the winding mechanism has probably decreased. Wind the wheel up again and test the feeding once more.

Is this magazine suitable for a GBBR SR25?
