Home Forums Hunting & Shooting Gunsmithing Removing a aftermarket muzzle device

I am wanting to remove this off of a Husky 30/06 I inherited. Not really a lot of sentimental rifle as is was a inherited, inherited rifle. I have tried heating and also unscrewing. I didn’t want to mess anything up so I only put a half assed try to it.
Anyone familiar with this brake(?) and how it’s installed?
Marked REX -SHA-CUL
Help is appreciated
