Description

HI CAP magazine for VFC / Umarex HK416 and M4 GBBR made in our workshop. Build with an AEG HI-CAP PMAG with an and a VMAG VFC GBBR magazine. The two magazine are joined by MagLink magazine type coupler. This magazine gives more autonomy while taking advantage of the GBBR recoil. 

About the HPA valve fitting :

  •      “High flow” type with a large diameter for the air flow: will allow you to fire full auto without loss of charge
  •      Anti-return system: keeps air in the magazine when disconnecting the supply hose, so possibility of using green gas also.
  •      Choose your EU or US version

Technical details :

  •      With this modification, the empty mag stop firing system no longer works.
  •      Magazine is delivered assembled and tested before sending, so you will still find BBs in the hi-cap :)
  •      Only compatible with VFC / Umarex HK416 and M4 GBBR
  •      Fitting installation is done with chemical sealing, it is not intended to be dismantled.
  •      Max pressure 130 PSI

Best HPA Adapter i have had
I tried 2 HPA Adapters from different Companies and none of the worked as well as this one. Even with 90 PSI it shoots very well. If you are looking for a reliable HPA Adapter this is perfect.

Great product
Ran this with 95psi on HK416A5 setup for Green Gas, 0,30gr bbs at 1.18/1.20 joule. This mag is fantastic for providing the ability to lay down covering fire or mowing down targets through bushes like AEG users do but with the realistic blowback from your GBB. Not to mention way more stable fps and higher refresh rates than Green Gas mags provide even with single shot firing!
