I would like to remove the muzzle brake from my Model 10 FCP-K .223.

There is an upcoming Canadian MOA challenge I may attend and brakes are a no no. I know I could pull it off and look but I hate to start wrench twisting on a good barrel and I've not completely made up my mind to compete there as yet.

If it is a straight forward removal and a normal thread I would remove it and replace with a thread protector.
Does anyone know the thread size diameter and TPI? I know standard is 12"x28 tpi for .223 so what say you?

Thank in advance.
