I know a lot of installers have been involved with Golf Sims, but what about Gun Sims? I have a client that has a golf simulator, but doesn't play it all that much anymore. He wants to have a gun simulator like police/military may train with, but with more of an entertainment aspect rather than training.
He's not looking for something from an Xbox, or PS4. He definitely wants authentic, and like many of our clients, money is not an object.
The only one I can find that looks pretty good is this one: [Link: gunfightersimulator.com]

Anyone with experience with this? or others?
