"Big bore" meaning over .40. And AR-10s, not AR-15s. Big bores for the -15s have been hashed over repeatedly here, as the last hour of searching showed. I remember reading somewhere a thread about a few big bores intended for the big brother of the AR family. I couldn't find it though, so it must not have been here.
So, what big bores do they have for the ar-10, and are any of them in commercial production?
