I am curious what barrel company is being used. "Match grade SS" doesn't carry much weight when considering the options out there.
Curious also..
No matter who you buy a rifle from with an accuracy guarantee .......inquire as to the details of the guarantee.
Come on now, they're all guaranteed to shoot sub 1/2 MOA with a custom load when shot in a climate controlled shooting tunnel by a world champion shooter. It's right there in the fine print. 
That said, I've never seen an Rbros rifle that didn't shoot well.
Copy/paste from their website:
Accuracy and Function
Accuracy and Function Guarantee what you can expect from my rifles
Each build is broken in and test fired under field conditions. This means with a bipod and prone on the ground. The rifles aren’t bench guns, so why would we test them that way? I, Travis Redell, personally test all rifles under real world conditions out in the open environment. Some might think this is crude, but I want to make sure that you never have any problems under field conditions. Customers receive a test target, dummy round and load data along with the rifles. This is why I am able to guarantee, without a doubt, that your rifle will shoot .5 moa or less, with sub ¼ moa being the norm, as fired by myself during the barrel break in. This is at no additional charge to the customer.
