For the first time since the introduction of the iconic and standard-setting M4 in the 1990s, Colt Defense is offering a rifle to law enforcement and civilian shooters as close as possible in configuration to the M4A1 military carbine. The Colt LESOCOM rifle is ideal for any law enforcement officer, marksman or hunter looking for a firearm that is most similar to what is used by the military.

“Only two variations separate this rifle from what we currently package for the United States government,” said David Ridley, Vice President of Colt Defense LLC, one of the world’s leading designers, developers, and manufacturers of rifles and carbines. “The Colt LESOCOM is as close as a civilian can get to shooting the same carbine as those defending our country.”

What differentiates the LESOCOM from the M4A1 platform currently used by the United States Armed Forces is the LESOCOM’s longer barrel length and semi-automatic fire controls. The barrel is 16.1 inches long, and has a rifling twist of 1/7 RH. With the stock extended, this M4 carbine has an overall length of 35 inches. The LESOCOM is chambered for .223 Remington (5.56×45 NATO) and comes with two 30-round Colt magazines.


Standard on the Colt LESOCOM is a Matech® rear back-up iron sight for acquiring distances out to 600 meters, effectively. Also included on the LESOCOM is a Knights™ Armament Rail System, capable of accommodating the user’s preferred optics and accessories at the three, six, nine and 12 o’clock positions.

The Colt LESOCOM features an M4 buttstock, pistol grip and flash suppressor. For left-handed shooters, an ambidextrous fire control selector is standard on all LESOCOM rifles.

The semi-auto LESOCOM has a 16-inch barrel, with these main differences defined by the restrictions for civilian rifles separating it from our military carbine.
