Throughout the world today, Colt's reliability, performance, and accuracy provide our Armed Forces the confidence required to accomplish any mission. Colt's LE6940 Carbine shares many features of its combat-proven brother, the Colt M4. The heart of this carbine is its 16.1" chrome-lined barrel. With a 1 in 7" twist, ammunition selection is virtually unlimited. In addition, Colt teamed up with Magpul Industries to outfit this carbine with the most highly sought after accessories. Magpul MOE handguards, a MOE carbine stock, a MOE pistol grip, a MOE vertical grip, and a Magpul Back-up sight all come as standard equipment on this exceptional carbine. The LE6940P incorporates a unique articulating link piston operating system that reduces the inherent stress in the piston stroke by allowing for deflection and thermal expansion. It is specifically designed for ease of cleaning, disassembly, and assembly of parts. The flip-up front and rear sights are adjustable for both windage and elevation. Lever safety. 20-round magazine included.
