A magical piece of kit from a young Taiwan manufacturer MIT. This unique Glock series magazine extension unit is basically an extra piece of normal magazine which when added to your standard mag, will increase your BB capacity per magazine by 13 rounds. It’s a great way to get that hard to source 40rd extended mag that everyone keeps running out of stock. Cheaper too!

Your standard Glock mag is 26 or 27 rounds,so if you fit one of these beauties you will have 39 to 40rds at your ‘disposal’. Here’s the best part; you can add up to three units per mag. Yup, let that soak in :) You can adapt your standard 26rd mag to a mahoosive -and quite heavy- SIXTY-FIVE ROUND MAGAZINE. The unit has its own gas chamber, so you will not see a reduction in performance at all. In fact, some pistols have been found to kick a little harder, due to the increase in liquid gas and additional space inside for conversion from liquid sto gas. Clever stuff :)


Do Not overtighten the fixing screws or you will damage the thread and not have such a cool mag!

Important Information


All images, product contents and specifications listed are based on checks performed when a product is first listed and may differ due to changes over time made by the manufacturer. This includes package contents in regards to any 'extras' provided e.g. Sample BBs.

Items used in images to promote the main item (Holsters, Camo, etc) are not supplied unless listed in the Specification tab under 'Extras'. This includes attached rails, grips, scopes, suppressors etc. If no extras are listed, please assume none are supplied.

Unless otherwise stated in the Specification tab, Battery and Chargers are not suppplied.

Where supplied, Chinese batteries and chargers are warrantied to be not DOA (Dead on Arrival) only. We always recommend swapping out to a better quality battery and charger at the earliest opportunity.

Custom Painted products (Two-Tone) are non-refundable as these are painted to order. 

Unless otherwise stated, all products are sold singly.



Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).

No airsoft AEG is warrantied for use with an 11.1v LiPo or higher voltage battery at UK velocities (373fps or lower) unless specifically recommended on the product itself. Use of higher voltage batteries can cause failures and will negate any warranty implied or otherwise.


Wearable Items

We cannot offer a refund or exchange on articles bought and worn skirmishing that you subsequently feel aren't suitable. If in doubt, try the kit on in your house BEFORE you play as soiled items will not be refunded for this reason. Clothing worn next to the skin (Long Johns, Socks etc) cannot be returned for refund if worn at all. For sizing, simply place them next to you before physically putting them on. Would you like to wear someone elses soiled socks?


We cannot offer an exchange on pyrotechnic devices due to device failure or items that have been stored for long periods of time. We are unable to guarantee that the pyrotechnic device has been stored in a moisture free environment or used correctly in accordance with the manufacturers guidelines.
