The most effective muzzle brakes on the market just got better!  The Gen II muzzle brakes were designed with one goal in mind.  We wanted to bring our recoil reduction to those customers out there with currently threaded barrels.  These brakes make life much simpler.  There are no crush washers, flat washers, or Loctite required. Simply you and a crescent wrench. 

The Gen II Fat Bastard was designed specifically for the 338 Lapua and similar cartridges but is not rated for cartridges based off of a 408 Cheytac similar.
