The Colt M4 Carbine is a semi-automatic, direct gas impingement rifle chambered in 5.56mm NATO, serving as the definitive civilian benchmark and direct descendant of the United States military's standard-issue M4 battle rifle. This duty-grade firearm incorporates a 16.1-inch chrome-lined, button-rifled barrel with a distinctive military-profile grenade launcher cutout, a 1:7" right-hand twist rate, and a standard A2 flash hider. It is built onto mil-spec forged 7075-T6 aluminum upper and lower receivers finished in a matte black Type III hardcoat anodizing, historically featuring the iconic "M4 Carbine" rollmark. Operating on a reliable carbine-length gas system, the traditional layout comes equipped with dual-layer polymer ribbed handguards, a fixed A-frame front sight tower, a standard single-stage trigger, a single-sided manual safety, and an A2 pistol grip. The optics-ready flat-top Picatinny upper receiver ships with a folding Magpul MBUS rear sight and interfaces seamlessly with the adjustable 4-position collapsible M4-style buttstock. The rifle feeds from an included 30-round Magpul PMAG, delivering an out-of-the-box capacity of 30+1. Colt M4 Carbine 5.56mm 16" Bbl Semi-Auto Matte Black Rifle LE6920
