Don’t dive in too far, those rivets are the devil in the details.
Something you may like to see,
AK4774 operators union has a great video on their website that shows a quality build and the work involved, worth watching several times.
Personally I think the WASRs are still one of the best deals available.
However they are not up to the same standards of a custom, or semi custom build such as those by Rifle Dynamics or others.
In a rack grade gun, I still prefer the Hungarian (FEG) AMD-65 folders.
