They did actually have a milled version of the straight stock, I've seen the parts kits, but not the underfolder They are uncommon however. I love my Yugo underfolder.Not a bad review except the Yugos don't have milled receivers.
They are 1.5-1.6 mm stamped steel.
Which makes them somewhat tougher than the standard 1.0 mm Eastern European receivers.
