Hopefully he didnt torque it down over 30ftlbs. Once you go over that mark it constricts the muzzle and your accuracy goes to hell.
Typically i set my wrench for 30lbs and torque until its lined up or hits 30ftlbs. Since thats a non directional brake, meaning it doesnt compensate for bullet torque it should be lined up.
Kinda why i prefer to diy one simple jobs like this.
