What kind of muzzle brake is this?

[Kurtz]

This is the after market brake the last owner of my rifle had installed. Any idea who makes it?

Check your Brownells catalog. They have many different types.
I bought one several years ago from them that looks identical to yours. IIRC, it was manufactured by "Smith".
