Wel...
There are a number of cool guns on there, but it's not really a flash, is it.
And concerning the two twin guns, a lot of weaponry from Austria and Germany is very similar to other guns. Chinese weapons especially, the T56 7.62 FAL (wonderfully heavy gun) was re-designed as a 'Canadian' weapon and thousands were shipped to Germany. They look exactly the same, but the T56 had a 39 bullet magazine and I believe that most FAL guns sport around 20-30. The TT was based on the Chinese version of the Kalashnikov, which was obviously stolen from Russian design.
