The Colt LE6920MPS 16.1″ 5.56 NATO 30rd FDE is a factory-direct Magpul-equipped M4-pattern carbine built around a chrome-lined barrel and a 1:7″ twist for reliability across all 5.56 loads. It ships with Magpul MOE SL furniture, a rear sight, a vertical grip, and one 30-round magazine — ready for the range or the field.

Key Features

• Chrome-lined 16.1″ barrel with 1:7″ twist — Why it matters: Chrome lining extends barrel life and eases cleaning, while the faster twist stabilizes heavier bullets (62gr–77gr) for better accuracy at distance.
• Magpul MOE SL furniture set — Why it matters: The slim handguard, carbine stock, and pistol grip reduce weight and improve ergonomics for shooters with smaller hands or who run gear in tight spaces.
• Magpul MBUS rear sight and vertical grip included — Why it matters: You get a solid backup sight system and a foregrip right out of the box, saving you $70–$100 in aftermarket costs.
• Colt M4-pattern bolt carrier group — Why it matters: Colt bolts are shot-peened and magnetic-particle inspected (MPI) for strength, giving you the same reliability as mil-spec service rifles.
• Detachable 30-round magazine — Why it matters: You can start training immediately without hunting for a mag, and it’s compatible with all standard AR-15 mags you already own.

Who It’s For

This rifle is for the shooter who wants a trusted name in AR-15s with Magpul upgrades already installed. It fits the new gun owner who prefers a ready-to-run package, the hunter needing a light carbine for brush country, and the weekend competitor who wants factory reliability without building from scratch.

Pros and Cons

• Pro: Chrome-lined barrel and bolt carrier group give you long service life with minimal maintenance — a proven Colt build.
• Pro: Magpul SL furniture is lighter than standard M4 handguards and doesn’t heat up as fast during strings of fire.
• Con: The trigger is a standard mil-spec single-stage — crisp enough for duty use but not as light as aftermarket triggers from Geissele or Timney. Many owners upgrade it later.
