Colt M4 Carbine Magpul SL 5.56 NATO 16.1" 30+1 Semi-Auto Rifle - Matte Black

The Colt M4 Carbine Magpul SL is a modernized take on the legendary M4 platform, chambered in 5.56 NATO and built around a 16.1" chrome-lined barrel with a 1:7 rifling twist. This CR6920MPS-B variant runs Colt's proven direct-gas-impingement semi-automatic action and ships with a 30-round Magpul magazine straight out of the box, giving it the familiar controls and magazine compatibility that have made the AR-15/M4 family the most widely used rifle platform in the United States.

The upper and lower receivers are forged from 7075-T6 aluminum and finished in a matte black hard-coat anodize for durability and corrosion resistance. A2-style controls, a mil-spec trigger group, and the M4 government barrel profile keep this carbine true to the original M4 layout, while the Magpul Slim Line furniture brings a lighter, slimmer, more ergonomic package to the shooter.

Iron sights consist of a classic A2 front sight post paired with a Magpul MBUS rear sight, providing a rugged co-witnessed aiming solution that is also ready to back up any red dot, holographic, or magnifier optic you choose to mount. The Magpul MOE SL collapsible carbine stock offers adjustable length of pull, the A2-style pistol grip fits the hand naturally, and the slim-line Magpul handguard keeps the front of the carbine light and easy to manipulate.

Chambered for both 5.56x45mm NATO and commercial .223 Remington, this carbine is a versatile choice for sport shooting, training, duty, and defense. It ships with one 30-round Magpul magazine so it is range-ready the moment it is unboxed. Manufactured in the USA by Colt.
