MSR 10 uppers

[FrankW]

Bought the MSR 10 6.5, can the upper be swapped out if I wanted to go .338? I looked around and have not found any uppers alone for sale.

Savage doesn't sell just uppers, and given their MSR10 receivers are shorter than a standard AR10 anything other than a Savage upper isn't going to fit.
