Defictive threading - Timber Creek Beowolf Muzzle Brake

I've had to return this Brake 2X due to the inability to thread this onto my beowulf. The thread protector my rifle came with easily threads on & off but this Brake aligns onto the barrel & will not screw in more than a 1/16 then it locks up.
Because of there customer service (excellent) I've opted to receive store credit for a different item purchase.
All I & my local gun store can deduce is defective factory threading/tapping
