Built on Colt’s LE6920 platform, this carbine is chambered in 5.56 NATO and uses a 16.1-inch steel M4-profile barrel with M203 cut and a 1:7 twist for modern duty ammunition. The barrel carries the "C MP 5.56 NATO 1/7" marking and is paired with a carbine-length gas system for classic M4 handling.
The upper is a flat-top A3 with T-marked Picatinny rail, forward assist, brass deflector, and ejection port cover. Sights are iron: a fixed, F-marked A2 front sight base and an A2-style rear sight. The threaded muzzle hosts an A2 flash suppressor, and a bayonet lug is present.
Upgrades center on utility and ergonomics. The BCM MCMR-7 aluminum handguard provides a numbered top rail and M-LOK slots for accessory placement. A Magpul collapsible carbine stock and Hogue overmolded, finger-groove pistol grip offer a secure, comfortable interface. A vertical foregrip with an integrated bipod adds on-demand stability.
This semi-automatic, direct-impingement AR-15 platform accepts STANAG-pattern magazines and is finished with hard-anodized aluminum receivers. Capacity is 30+1, and controls include a manual safety. A padded MultiCam-pattern sling is included to round out the package.
