Everything is for sale
But, I don't think this rifle is anything special. You could just buy an ADL varmint for $430, or wait for a deal on the AAC. Looks like the MC3 deals are gone with DBM, but there might be some BDL versions left.
I might sell the McMillan Remington Hunter stock, as this rifle will stay in the MC3 as a dedicated target rifle. The MC3 is nowhere near as stiff as the Rem Hunter, but I put a 9-13" Harris on the rifle and shot at 954 yards without any issues.
