I've had one of these on order with James for a few months, and it's about ready to ship in the next month if I remember correctly.
Picking up a 26" MTU in .308 for an Origin, going in a manners prs1 with double dead fill. Burris dmr3 up top. Should be 18lbs running a hellfire brake. Whole plan is to have a simple and enjoyable rifle to shoot that doesn't require any fussing once setup. Picked .308 for that reason as I have race guns. Traditional stock with a .308, woooooof!
I am curious to see the difference in chamber heat as well as balance. The typical/barrel nut pre fit loses a ton of mass at the chamber, this is a 7lb Mtu vs the 5lb 4oz pre fit mtu, and all that weight is at the chamber.
