Thanks for the input. Wish I had more experience with different configurations. So far I only know what I don't like about the DPMS.

Got the White Oak site up. Might give them a call Monday. Can't find lowers on there site so that must need supplied by the customer?

I'm interested and with winter near it might be fun tinkering and learning. In the past I have paid premium tuition discovering what suits me.

What I'm after is a varmint rifle that will see a lot of range time. Enjoy shooting paper and trying new components. Hunting would be confined to groundhogs, crows, coyotes, and foxes.
