A little bit misleading
The building doesn't look like an AK 47, it just has some AK 47 features. I bet it would be easy to get in and out of, the doors would never jam. On the other hand, if you took the elevator to the 5th floor, you might get out on the 13th! And all the light switches would be hard to reach and difficult to operate!
and, of course the AK-47 is just a modified Stg 44, just look at them. IF you use the word modified to mean a different internal design.
I always did find it difficult to believe that Kalsnikov
never saw the German gun before he designed the AK 47. They are different, but considering how closely the external resemblance is I always found that line hard to swallow. Maybe he never got to
study the Sturmgewehr, that I can accept, but if he
never saw one, it is a fantastic case of parallel evolution.
