KWC Mini UZI 6mm CO2

Few weeks a go one visitor email me to help him/her to search for kwc mini uzi magazine lip, this remain me again of old memory how badly i wanna hold this baby.he.he.he. So i decided to buy 6mm bb's version.
And i receive it today

And under lower receiver i see this warning dembossed

It clearly stated due to high power, this gun use for targets shooting only, some review on internet says it has 500++ fps, this thing not allowed for skirmishing. So i decided to buy green gas adaptor for my magazine and do some upgrade (inner barrel and piston head). Review will update soon.
