Thanks for the pointer!You're better off going to gun shows, online deals (get your 03 FFL if you don't have one already!) or even better, finding private sales.
My experience has been most gun shops are overly proud of their milsurp C&R offerings.
Also note note all SKS rifles are on the C&R list!
That list only shows the Russian, Romanian and Albanian versions as being eligible.
However, per the ATF, "Firearms automatically attain C&R status when they are 50 years old. Any firearm that is at least 50 years old, and in its original configuration, would qualify as a C&R firearm. It is not necessary for such firearms to be listed in ATF's C&R list. Therefore, ATF does not generally list firearms in the C&R publication by virtue of their age."
So being manufactured before 1974 is all that should be required, but some gun shops may only go by the ATF list.
