Just a thought, but perhaps the poster could be done as four photographs with appropriate firearms for each caption? The FS2000 doesn't really fit the hunting category too well, especially given that many states have magazine and caliber restrictions in place. And while many of us use long arms for HD, I have found that most people tend to view rifles as offensive rather than defensive arms.
If it were me, I would do:
Security of a free state: Huband and wife standing with (AR,FS2K, M1A, etc) standing in front of their house with an American flag in the background.
Lawful self defense: Adult household member at the ready with pistol while ominous character can be seen somewhere in the dimly lit background.
Hunting: father and son walking through the field with rifles or shotguns and appropriate dress/gear.
Shooting sports: Any picture that depicts competitive use of firearms in a formal setting.
I do always like your posters, but being directed at the general population I think this one should play a bit on familiar, some-what PC images. Just my $0.02
