About Us
Our Vision
At Tier Three Group Gun Works Design's mission is simple to create a form fitting and logical suite of purpose driven AR, duty/defense handgun components with reliability and ergonomics as top design goals. A simple change in location, shape, or direction of serrations can make a great deal of difference to the way a user interacts with his firearm. Skills can't be bought, we endeavor to help trained and skilled users more efficient at their craft.
