Our Rapid Engagement Device, or better known as the Fortis RED, is a brake that stays true to our brand. We wanted to develop, engineer, and design a military grade accessory that not only functions great, but looks great also. Tested and evaluated by people in the military and law enforcement community - then put to the test by members of the 3 gun community, we came up with this design. Tested under harsh full auto conditions, the RED doesn't disappoint.Keep your speed and accuracy up. Put more down range and on target.
