I have an ok FSSF impression and a few others.
I am on a short hiatus from airsoft at the moment but I am 100% positve that Leecas and others will post over the next few days.
There are at least 2 of us that can do FSSF, maybe more. If you have any questions feel free to ask.
There are pics of some of my FSSF kit from another thread.
