The guys at ADM really hit a grand slam with the Mod 2 and took the "Improved" in Universal Improved Carbine (UIC) to a new level. They improved and upgraded just about everything you can think of on an AR15 right out of the box and made it one of the most feature rich AR15's on the market. It's no wonder these have quickly become one of our best selling rifles. If you value your hard earned dollar, you'll definitely want to check this one out!
