The Gen 2 Series of brakes features a nut that is a separate piece that allows you to install the brake at home. Installations take about 30 seconds and have no hideous crush washers or peel washers to deal with. It is precision machined out of high-grade stainless steel. The LB is a perfect fit for barrels .750 - 1.0 inch in diameter at the muzzle.
