Price Check I believe its a Polytech despite the non hooded front sight. Not drilled.

Yes, I am using one of these on a Type 56 build right now. It is supposed to be for the Legend which has the open hood

Measure the barrel.
23mm akm
22mm ak100
19mm Chinese

Thanks man,Ya it's got Chinese markings but wasn't sure about anything else. Do you know about what this might be worth?

You can still buy them in a cosmoline bag from Polytech for $550
