Stamped receiver sks is very rare. I was referring to trigger group and other parts.
The sks I got a couple years ago is all machined, and is a military one according to cgn users. It's tough as snot. Everything fits nice and tight.
Not sure if all Military SKS rifles use only machined parts. SKS rifles seem hard to pin down, pretty sure the earlier they were made, the more machined parts were used and the better the fit and finish were.
Maybe curtton will chime in and straighten things out.
Military ones are known for tighter tolerances it seems. Function wise, the same. More bragging rights with a military one.
