I'm not really thinking of a business as such. I know for a fact that there wouldn't be enough money in it to pay my rent anyway. And yes, you're right about turning a hobby which is fun into pain in the mag pouch.
How much will people pay? Well I can see people on here with genuine SUSAT and ACOG sights mounted to the top of airsoft weapons that have a range which I would have thought would fall below the minimum setting of the horizontal graticule of these systems. This indicates to me that people take this quite seriously.
I deployed to Irag with iron sights believe it or not, so ACOG sights for airsoft are a bit extravagent no? However, if people get enjoyment from modifying their rig, or satisfaction from obtaining and setting up such systems, and paying so much attention to every detail, who am I to question their enjoyment?
In MY experience, people will use watever old crap they are fed, so long as they don't know any better. There are multiple threads on here and all the other forums where people fail to understand CTCSS usage and think that 500mW is 500 Watts. Its a fairly complex subject, and not to everyones liking. And so, people think that an Argos binatone will be ok for airsofting, when it is anything BUT, judging by peoples comments of "I plugged this in and it doesn't work" "how can I get more range" "my radio is dead".
Airsoft is quite a "robust" hobby. Your kit takes a kicking. If someone made a 446 unit with a solid aluminum case, rugged connectors, 3ah lead acid, speech inversion, removable antenna and a decent, sensitive front end, I would buy one, and so would every one else.
No one DOES though, do they?
