I found used SAM-7 7,62x39mm. It has FN-FAL style flash disperser, milled receiver not marked 'Cricle 10 or Bulgaria', no side rail mount, fixed stock and nicely polished trigger marked 'B'. Serial AB 04 00xx. It is very well made throughout and trigger pull is excellent for an AK-47. Can you give some feedback good or bad? Does anyone know the vintage of this rifle? thanks.
