This adapter is designed specifically for the Umarex/VFC MP7 to allow easy conversion from gas-in-mag to a external regulated HPA (high pressure air) or Co2 supply with minimal extension from the base of the magazine, unlike some other adapters an o-ring is used to create a reliable seal.
This is US type adapter and is compatible with Foster Series 2 and most other US type couplers, these will not fit Balystik US type couplers.
HPA or external regulated Co2 supplies virtually eliminate cool-down which gives much more consistent performance and allows gas guns which would normally struggle to function in colder conditions to function normally.
Installation is simple but does require the fill valve hole in the base plate to be enlarged slightly to 8mm, this is best done with a stepped drill bit and a low speed drill. Once done simply remove the fill valve and replace with an o-ring, refit the base plate then push the adapter through the o-ring and thread it in by hand until it makes a seal. Stepped drill bits are available to order in the tools category.
Each adapter is fully CNC machined from a solid bar of 6026 T9 aircraft grade aluminium and is anodised black for additional corrosion and wear resistance, 4 o-rings are included with each adapter.

Warning – The airline pressure to the adapter should not exceed 145psi/10bar or the recommended pressure for the magazine. It is the responsibility of the user to ensure that any HPA or Co2 conversions comply with local laws and airsoft site rules.
