I' ve never shot one myself but I' ve seen a few at the range. Seemed to function ok for their owners in .308 and 7.62x39.
Accuracy seemed decent the only draw back is that crude rear sight.
If I got one in .308 I' d scope it with either a low-power like a 1X or maybe a red-dot.
But, I should add .223 AK' s seem to have a bad rep for reliability. Not so much the Saigas but some like the Romanian SAR' s. I think it has something to do with the mags but I don' t remember the specifics.
Myself I want one in .308 but am trying to wait to see if the AWB goes away so I can get one maybe with a pistol grip and a 20rd magazine.
