M59/66 Series of rifles. A lot of people on the net are not really aware this difference. In this first pic the top three are totally new/unissued
M59/66/A1 Rifles. Bottom is an actual Mitchell M70 Yugo.

The following pics are of the true M59 version. The M59 was the first Yugo SKS rifles built. They are few in number compared to the later versions.
But, like all Yugo SKS, built like a Tank. The M59 does not have a chrome barrel nor do the later versions. Top quality barrels. I have one in particular that out shoots my Chinese, Romanians, and Russians big time. Personal feelings are that the non-chrome barrels have an edge in accuracy. FWIW.
The rifle shown I just received this month from Samco. Graded VG. Actually, its higher than that. Notice this one has fully machined serial numbers
on the receiver and bolt carrier. Not the usual run of the mill M59 which normally has a refurb. electro-pencilled number on the carrier. Better rifle than described or I ordered in fact. I am pleased with this one certainly. It has not been cleaned as of today either. Right out of the box as received.









So, this is the difference between the Yugo SKS rifles.
