I'd like to know what other calibers(Not 308) are offered in the AR15 style rifle. Make or brand doesn't matter, but I'd like some input if you have a "unique" caliber. How about any 204Ruger??
Are there any semi-autos in 204Ruger? How about 50 caliber? Is this too strong for the action and receiver? (Not bolt action, but semi-auto). Didn't I see a 300 in an AR15?
A few that come to mind, I'm sure there are others.

Thanks Parrandero, Do you happen to know of a few brands(of the rifle) in these calibers?
Are all of these of the AR15 style AND semi-auto?
Not so senile anymore, Dave
