Which 30 Cal Muzzle Brake

[jam66]

I ended up with these 2 brakes. I’m not sure which is the better brake(left or right?) I will be using these on a .308 bolt action. My first consideration is which will have the the lower muzzle blast followed by lower recoil. I would sacrifice some recoil reduction for a lower muzzle blast. Both are new so I would rather just go with one and sell the other.
