Most accurate 20 inch barrel

[Heinrich]

Hey guys, just starting a 308 build here and was wondering what barrel to get. I've heard 20 inch are the most accurate, waiting to get the best accuracy for my buck, I found a 20 inch ballistic advantage for a decent price, anyone have any experience? Aero precision M5 308

Thanks!!

The Fulton Armory M110 barrel. Nothing else in 20" is gonna touch that, unless you spend some major bucks on a custom barrel.  That's the one.
