Colt LE6920 M4 Carbine 5.56 NATO, 16 in M4-Profile Barrel, Magpul MOE Furniture, ARMS #40 Rear Sight
This Colt LE6920 M4 Carbine stands out with correct factory markings and proven M4 features. The receiver is rollmarked "M4 CARBINE CAL. 5.56MM" with the Colt logo and COLT wordmark, and the right side reads "COLT DEFENSE HARTFORD, CONN. U.S.A." The barrel is marked "C MP 5.56 NATO 1/7." It has an LE-prefix serial, a flat-top upper with T-marked Picatinny rail, and comes configured with Magpul MOE furniture and an A.R.M.S. #40 flip-up rear sight.
The 16-inch M4-profile barrel uses a 1:7 twist to stabilize a wide range of 5.56 NATO projectiles. It runs a carbine-length gas system for standard M4 handling. The muzzle is threaded and fitted with an A2 birdcage flash hider. A delta ring assembly is present for handguard retention.
Up top, the flat-top receiver includes T-markings on the Picatinny rail. Sighting is handled by a fixed A-frame front sight base with bayonet lug and an A.R.M.S. #40 low-profile flip-up rear sight installed. The carbine is set up with a Magpul MOE carbine-length polymer handguard, a Magpul MOE 6-position collapsible stock, and an A2 pistol grip.
Colt’s barrel and receiver markings provide easy verification of key features and origin. The included 20-round USGI-pattern aluminum straight-body magazine complements the 20+1 capacity.

The LE6920’s markings and LE-prefix tie it to Colt’s M4 Carbine lineage. The "C MP 5.56 NATO 1/7" barrel marking indicates Colt’s Magnetic Particle inspection and 1:7 rifling. These are hallmark identifiers buyers look for on factory-correct examples.
Core M4 features are present: a 16-inch M4-profile barrel, carbine-length gas system, threaded muzzle with A2 birdcage, and a delta ring assembly. The fixed A-frame front sight base includes a bayonet lug as expected on this pattern.
The flat-top upper with T-marked Picatinny rail provides standardized mounting positions. The installed A.R.M.S. #40 rear sight pairs with the front sight base for a ready-to-use iron sight setup.
Magpul MOE furniture updates the rifle with a carbine-length polymer handguard and a 6-position collapsible stock, while the A2 pistol grip maintains a traditional control interface. Capacity is 20+1 with the included 20-round USGI-pattern magazine.
