I'm having a slight existentialist crisis. Well, not really, I just never get to use that phrase. Anyway, I have a small collection of AR-15s, some built with a specific purpose, some just got built because those lowers in the safe were calling out. I've got a dedicated 3 gun AR in .223 Wylde, two 5.56mm pistols and two .300 BO pistols. I also have a bolt 6.5C for long distance play and a tricked out 10/22 for rimfire plinking. I somehow feel that this is a suboptimal mix of ARs and I'm trying to decide how to get a more optimal mix.

For those who owned multiple AR-15s before the canoe accident, what did you own and why?
