The Colt M4 Trooper 5.56mm 16" (aka Colt Trooper Patrol Carbine) .223 Remington/5.56 NATO chambered semi-automatic is an upgrade to the civilian version of the Colt M4 issued to the US Armed Forces

The all-black gas-operated gun uses a 16.1” long chrome-lined 1:7” twist ratio barrel fronted by an A2 birdcage style flash hider. It has a standard trigger and a reversible safety. It also uses an A2 pistol grip and an M4 buttstock. The 4-position collapsible stock means overall length ranges from 32” to 35.5”. The carbine weighs 6.95 pounds.

The receiver is strong and lightweight aviation-grade 7075-T6 aluminum. There’s no carrying handle, which permits topping the receiver with an integrated MIL-STD-1913 Picatinny rail. Sights aren’t included, so you can add your own!

This M4 upgrades the well-known Colt M4 Carbine by adding the free-floated Centurion Arms M-LOK forend Centurion designed just for the Trooper. This 13” long ruggedly engineered forend features M-LOK slots at 3, 6 and 9 o’clock and is crested by a long Picatinny rail at 12 o’clock. It connects to the rail atop the receiver making one long continuous crenellated surface.

The gun has a 30-round Magpul PMAG magazine making capacity 30+1. The Trooper is restricted in California, Colorado, Connecticut, Maryland, Massachusetts, New Jersey, New York, Vermont.
