No name is known as well as Colt when it comes to reliability, accuracy, and performance in an AR. For years, The United States Armed Forces have put their confidence in the Colt to help them accomplish any mission. Colt is where “mil-spec” truly begins. With its 16.1” chrome lined 1/7 twist rate barrel, the Colt LE6920MPFDE can handle almost any ammunition selection and stabilize popular heavy loads. A true M16 Bolt Carrier Group with a properly staked gas key and shot peened bolt is included. To make things even better, Colt collaborated with Magpul Industries to outfit the industries already best-selling AR with highly sought after AR furniture. A Magpul MOE handguard, MOE vertical grip, MOE pistol grip, MOE carbine stock, and a Magpul MBUS rear flip-up sight all come standard. Like its combat proven brethren, the Colt LE6920MPFDE semi-auto rifle includes the durable and adjustable post A2 front sight. Don’t settle for anything less than the best.
