No, they came with a standard beech hardwood stock and a Century Arms black poly pistol grip, not a butt hole stock.
Because of the way the import laws were at the time, they were imported as "barreled receivers" with the stock removed from the rifle but in the box with it. This way they didn't need the SVD style stock that came on the WUM, Romak, and very early WASR rifles, and didn't have to be imported as a single stack magazine rifle like the WASR which was then opened up to standard double stack here.
Once Century received them, they put the stocks back on and added their pistol grip. They also replaced the semi-auto Romanian trigger group with a lower quality one of their own manufacture, many of which were infamous for the painful trigger slap they caused. So other than the ground bayonet lug, no muzzle threads, Century grip and trigger group, and I believe US gas piston (I'll have to check on that one), these are a semi-auto version of a standard Romanian military issue AKM of the period.
Get a nice Romanian Bakelite grip and a Romanian AKM trigger group, and these can be easily restored back to correct original Romanian military AKM configuration.
Nice original, un-dicked with SAR series rifles are very desirable and collectable, and are steadily increasing in collectability, collector demand, and value. Putting a gas block with the bayonet lug intact on one or carefully welding and reshaping the lug on the rifle, and threading the barrel or adding a Romanian front sight and muzzle device assembly on a SAR-2 won't detract from value or collectability, at long as it is done well and carefully. Since they are a standard AKM rifle, the stock set can be changed out for other stuff like Romanian, Polish, or Russian laminate, side folders, black or plum poly, "tactical" crap, etc. without damage or modification to the rifle.
The original stock and handguards are rather scarce and sought-after, thus have some value, and should not be refinished or discarded if present.
