Barrel rotating on my new sub 2k

I was trying to put my muzzle break on and as soon as I started the barrel started rotating. I can’t even turn the muzzle break now. What do I do?

Hi jeff and welcome. Picture of the barrel please?
Did you remove the stop nut from the back of the thread protector? .

I removed the thread protector from the rifle, put the crusher on, put it on the vice, then when I started rotating muzzle break on, the barrel started rotating with it. Now the barrel can just twist all round

Did you buy it new or used? Gen1 or Gen2?

The vice is s’posed to grip the barrel. The vice is called for to prevent you from stressing the plastic durimg install.

I think you need to seek assistance from Kel Tec or MCARBO. The Sub barrel is torqued into a plastic pivot - at a minimum., this needs reset but I suggest you have it inspected by a pro before firing again.

Thanks. I was hoping that there was something I could do and not have to send it in

Try your local gunsmith first, maybe he/she/they/them/it can lend a hand.
