Defence Required


Wanting to use a shotshell magazine with your TM MP7 GBBR? AIRTAC have reverse engineered & manufactured our own short magazine, then put our awesome shotshell mechanism inside!

A BB latch to prevent dropped BBs and simple push mag release on the rear of the adapter makes it an absolute dream to change shells.

Shotgun shells are almost the exact width of the MP7 grip, hence for the shells to eject well out of the adapter, you must remove the stickers from your shotgun shells, and gently lubricate the inside of your MP7s grip with a medium silicone oil.


  • Lightweight magazine setup without an obvious HPA adapter aesthetic

  • Modelled around a HK 30 round MP7 Magazine

  • BB retention mechanism to reduce BB loss during magazine changes

  • US style fitting as standar

    Why shotshells?

    • In the UK, some sites do not allow adapters that ‘stick out the gun’.
    • Far more convenient than an M4 adapter when used as a holstered HPA sidearm (due to ‘extended baseplate’ profile)
    • For DMR/Sniping builds, allow you to get low to the ground
    • Use one mag for pistol and shotgun nights!

    Shot Shell HPA Adapter Info

    • Compatible with most airsoft shotshells. We recommend CYMA shells, as they have the strongest springs (TM Shells are not as good)
    • 0 BBs are dropped when shell is empty (adapter will feed all 30 rounds of shell)
    • A higher PSI and heavier BBs are required to hit higher joule values due to the smaller internal volume of the adapter. Field limits are still very much achieveable at green gas pressures, 120-135PSI


A valid defence is required to purchase any Airsoft Replica Firearm. If you don’t have a defence you must add Two Tone to your basket.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

To purchase a realistically coloured Airsoft Replica Firearm (RIF) you must have a valid defence.  The most common of these is UKARA which stands for United Kingdom Airsoft Retailers Association and is essentially a database of registered players.  UKARA requires you must be a site member at any of the registered UK Airsoft sites.  This means you must play 3 games in MORE  than 56 Days. Once you become a member you are added to the database, please note paperwork and validation is required.  There are other types of defence, but UKARA is by far the most popular.  Please note this only applies to the gun, not the kit or accessories.

If you don’t yet have a defence, you can always add two-tone to your order. This simply means you have 51% painted in a bright colour such as green, blue or orange.  You can then purchase any RIF you wish.

If you have any questions regarding what is or isn’t a defence, or just looking for some general airsoft advice, then please drop us a call or contact us here
