The Colt LE6920 M4 Carbine is a civilian-legal semi-automatic rifle that mirrors the design, handling, and performance of its military counterpart—the combat-proven Colt M4. Chambered in 5.56 NATO, the LE6920 features a 16.1-inch chrome-lined barrel with a 1:7 twist rate, allowing it to reliably stabilize a wide range of bullet weights, including heavier projectiles commonly used in tactical and precision shooting. Topped with an A2-style flash hider, the barrel is built for durability and consistent performance under prolonged use. This model retains the classic A2 front sight post and an adjustable aperture rear sight, offering dependable, field-proven iron sights for shooters who prefer traditional marksmanship or wish to co-witness with optics.
 
The LE6920 is built with a collapsible buttstock and ribbed polymer handguards, providing the shooter with lightweight maneuverability and a familiar M4-style profile. The forged 7075-T6 aluminum receivers, finished in matte black, meet mil-spec standards and ensure long-term strength and corrosion resistance. Colt’s attention to detail in manufacturing—such as magnetic particle inspection (MPI) of the bolt and barrel, chrome lining, and a carbine-length direct impingement gas system—gives this rifle its reputation for reliability in adverse conditions. Whether used for law enforcement, defensive applications, or civilian training, the LE6920 delivers the trusted performance of the M4 platform in a package that's rugged, accurate, and combat-ready.
