The Badlands Integrated Muzzle Brake and Blast Deflector comes in two thread sizes. This item is BAD and out clientelle loves them!
This is from the manufactures website, they explain it best in my opinion.
'Made from high strength 17-4 stainless, heat treated to H900 and then nitrided with a QPQ process for extremely high corrosion resistance The combination of the material, the heat treat process and the hard coating enable Badlands to withstand full auto fire.
The internal muzzle brake helps reduce recoil and muzzle rise by uniformly dissipating gasses through coned ports that counter recoil. Taming the dramatically expanding gasses associated with muzzle blast.'
