Here have been some of my entries:
My Rhodesian Homage Rifle
My FN-FAL in grey homage rifle
A gunfighting carbine in grey
Another variation of the above design
I call this one the Pugio
This is the DeSPR or Despair for short. It was specifically designed to mate with the Primary Arms 1-6x scope. Link here.
I call this the "Tosh" after the character Tosh from the movie The Wild Geese.
Didn't win. Not even top 10. Oh well, there were over 3,000 entries. I am disappointed though.
