Caps for me seeing not shouting

im in the process of changing out my ar10 308 20 inch barrel.... I know the bcg is proprietary, but i thought i would be able to at least swap out the barrel... I ordered a faxon barrel that looked compatible, but the gas port is not in the same place as the savage... And the port is smaller... Im now in the process of having a custom barrel made....

Any way, i called savage, they will not sell any parts for the ar10. I asked how much would a barrel and matching bolt cost, they did not know...
My question is ....is there any company that sells parts for the savage msr10?

Funny, i vave a 110 in 308, and can get almost anything after market for the gun.... Maybe sad...
