Stag Arms' Model 3L AR-15 chambered in 5.56 NATO was designed specifically for the left-handed shooter from the ground up with input from law enforcement officers who are left handed. By putting engineers and professional shooters together, you get a unique rifle that is nothing like anything the AR-15 market has seen before. The Model 3L is perfect for left-handed shooters that are looking for a rifle that doesn't throw hot brass in their face. As with all Stag Arms rifles, the Model 3L is tough enough for anything that you could put the rifle through. They just work. Everytime.
