So you weren't paying attention when this was discussed endlessly regarding bob vogel's gun last year? If it's not functioning, it's not considered a light by uspsa.
If I have a cmore on my gun, but take the battery out of it and the electronics, am I in limited or open?
Taking the engine out of a car doesn't mean it's not still a car, it's just a non functioning car, just as taking the guts out of a flashlight doesn't change the fact it's a flashlight, it's just a non functioning flashlight.
The rule says attached flashlight is not allowed in limited.
I think if you took the lens and batteries out of a C-more it would be pretty easy to make the argument that it is Not an optical sight but just a really bad sight and legal in limited. I think the key would be removing the lens.
