This adapter sits inside the GHK G5 mag-well, and protrudes only to reveal the CNC aluminium mag release paddle, and the US style HPA fitting. You must glue the feed lip pins in place
A donor mag is required for feed lips, exhaust valve and gas route. A CNC valve collar ensures lifelong air seal. Please see the product images for the correction feed lip version (note the position of the two side wings on the lips)
Designed and tested with the CYMA MP5 Mid-Caps listed on our website.
350fps@105psi. Due to sacrificing volume for a low profile design, this adapter will only cycle a few rounds on full auto (some regs will fair better than others!), and is best suited to semi only gameplay, where you will not experience a single issue, and will cycle and feed perfectly! You can absolutely spam semi as fast as you can, all day long.
You will need a GHK valve key for home installation. Diagram to follow, though you’ll almost certainly figure it out on your own, the intelligent person you are ;)
Apologies for not providing the gas magazines for this adapter, but as I’m sure you all know, GHK G5 mags are somewhat hard to come by!
