kingkrollI have no idea on the history of this, but it was manufactured by Krebs Customs who is very well known for high end AK builds. It's interesting in a number of ways. It's built as a short 51 style on a JLD receiver, but still uses a 16" barrel. Less noticeable is that the entire receiver is shortened by about an inch. This is definitely an unusual build and would be great for any HK collector.
