I just got a call from Colin Stolzer. He has a customer that has an Olympic arms AR in 22-250.
I looked it up and yup..........he's right.

The down side is they are using the old 1-14" twist, so this is not going to shoot the long heavy VLD type bullets, but I'd bet they could be talked into making one with a 1-8" twist.
So they were ahead of me on that.
