One of the most important considerations is the thread pitch at the muzzle, I believe it is: 5/8"x24; however, please verify.
Second, consider the port pattern. Radial brakes work great; however, the don't work well if shooting from prone - kicks up a bunch of dirt and debris, 45' horizontal ports work well for recoil attenuation; but, are hell for shooters to your sides. Apical (top) ports are important for recoil attenuation also; however, in single shot firearms, in hunting situations, not essential for recoil attenuation, unless you wish to visualize shot hit and placement (depends upon caliber and distance to target.
This is a brake that I use extensively, on many of my guns, including on my CVA Scout V2 in 6.5 Creedmoor:
