I bought this off a friend along with a job lot of other parts as he was downsizing his collection but never got around to doing anything with it. I'm not sure what the brand is or what model of Bizon its for but if I had to guess I'd say its the PPS version so it might take some tinkering to mod to fit other brands or ordering more PPS parts from overseas to complete. 

Consists of:
Receiver (has rail side mount, trigger guard, pins etc).
Dust cover,
Handguard
 - All metal and like new, never been fitted to anything except loosely to one another. They have been stored together though so will have the usual surface scuff marks from the three parts clanking against one another.

Its worth noting that the folding stock button doesn't seem to have much spring to it or is a bit stuck with friction so will need some attention.

Sadly I can't really offer too much more info because I'm a bit clueless but if you have any questions please do ask and I'll try my best to answer them.
 

Very much open to offers.
