Armson Semi?

[SniperFox]

I just purchased an Armson Semi from a buddy from South Africa and need some info on armson if anyone has anything. It looks like it might take mag parts or at least o-rings, it has the same blow forward design and disassembles the same. Does anybody know anything about these or where I can get replacement parts? Anybody deal with Armson customer service before? Any info would be appreciated!
Thanks
