GAP 6.5 Saums Xtreme Hunter Vais muzzle brake size and thread pitch

[TBass]

I am looking to swap out the radial Vais muzzle brake that came with my GAP 6.5 Saums Xtreme Hunter to a directional muzzle brake. I lack the tools to measure thread counts. Can anyone tell me the size of muzzle brake I need to replace it?

Extreme Hunters are 1/2x32 threads

Thank you very much!
