A 6.5 Grendel-type bolt carrier group and 6.5 Grendel / ARC-family magazines. A standard 5.56 bolt will not work.

What twist rate does it use?

A 1:7 twist, fast enough for the long, high-BC bullets .22 ARC is built around.

Are a BCG and charging handle included?

They are optional add-ons you can select when ordering; the upper itself ships without them.
