My heavy b14R sits in an ACC premier. I have mlok weights up front, and the balance is perfect. These rifles punch way above their price point. Especially now that they can be had for around $650. Throw a Timney or trigger tech trigger in it, and you are a good ways to having a highly competitive rifle.
I’ve also had the barreled action in an MPA hybrid with competition rails, and the balance is just about the same as the ACC in a lighter overall package.
