I gotta admit, the first time I saw b&w pics of E.German AK's in a couple of books, I thought they were extremely cool.
So I picked up a set for $35 at a gun show a few years back and promptly modified it to fit a Chinese .223. First impression? The composition of the plastic itself is cheesy. While the bakelite lower handguard seemes decent enough, the upper handguard led me to believe it would melt---quickly! (it didn't)
The buttstock? Well, I have to admit I think it looks alot better in b&w than in living color. It is , for the most part, hollow. The pistol grip seems to have more "flex" to it than others I have as well.
In the field, I noticed an increase in felt recoil. Others dispute that claim, but I know it felt different than it did both with wood thumbhole furniture and Chinese polymer. (those sets are both harder and heavier than the E.German set)
My conclusion is that it would be perfect for a MPi-KM clone or a "brush gun". A good deal for the money, however if they were truly desirable they would cost twice as much.
