Northland Shooters Supply and a CBI (Criterion) barrel is a good place to start.

I bought a couple barrels, nut, lug and wrench from them, EXCELLENT SERVICE, EXCELLENT PRODUCTS!!!
 
I have had good luck with several Criterion barrels from NSS. All have been around half moa with a little load development. They might do better with a better trigger puller running the gun. James at NSS has taken the time to talk with me about options. He seems to be stand-up guy.
