AR 10 build question

Guys

I hope there are some gunsmiths on the boards that can answer this question.
We all know that uppers and lowers of different platforms are essentially interchangeable.

I want to build a AR 10 (.308) with one lower and two seperate uppers. One upper would be 16" barrel in .308 and the other upper would be a 7mm-08 in a 22" barrel

One for close shots and the other for distance. I already have a spiced up Savage .308 bolt action for distance and I love it. The 7mm-08 is for target and the .308 is for hunting (probably hogs). Anyway my question is :

From an accuracy and fit standpoint, should I try to place the order for the stripped lower and the two stripped uppers to be machine matched? Is that important? Or just buying the stripped lower and uppers from the same manufacturer good enough?

Thanks in advance for your responses
