Colt M4 Carbine Magpul SL 5.56 NATO 16.1" FDE

The Colt M4 Carbine Magpul SL: Purpose-Built Performance

The Colt LE6920MPS represents a straightforward approach to the modern sporting rifle. This is a carbine designed for those who want a quality foundation without unnecessary complications.

Core Design

The rifle features a 16.1-inch chrome-lined barrel with a 1:7 right-hand twist and six grooves. The barrel is finished in manganese phosphate, a proven protective coating that has served military and civilian shooters for decades. The upper and lower receivers are machined from 7075-T6 aluminum and finished with black hardcoat anodize—a durable, corrosion-resistant finish.

Ergonomics and Controls

Colt has equipped this carbine with Magpul's SL (Slim Line) furniture throughout:

• Handguard: Magpul MOE SL for a comfortable, lightweight grip
• Buttstock: Magpul MOE SL with adjustable length of pull (33 to 36.5 inches overall)
• Pistol Grip: Magpul MOE SL, ergonomically designed for control
• Vertical Grip: Magpul MOE SL for positive hand placement

All furniture is finished in Flat Dark Earth, a practical color that blends well in varied environments. The reversible safety selector accommodates both left and right-handed shooters.

Sighting System

The flat-top upper receiver accepts modern optics and accessories. The rifle ships with an A2 fixed front sight and a Magpul MBUS rear sight—both proven designs that provide a reliable baseline for shooting. Should you choose to add a red dot, scope, or other optical device, the flat-top receiver is ready.

Trigger and Operation

A single-stage trigger provides straightforward, predictable break. The rifle operates via direct gas impingement, the time-tested system that has proven reliable across millions of rounds.

What's Included

The package includes a 30-round Magpul PMAG magazine and a manual cable lock. You have everything needed to begin shooting responsibly.

The Bottom Line

This is a rifle built to work. No unnecessary features, no marketing gimmicks—just solid engineering and proven components assembled by a manufacturer with over 150 years of firearms experience. Whether you're new to the sport or adding to an existing collection, the Colt M4 Carbine Magpul SL delivers dependable performance at a fair price.
