The Colt M4 Carbine chambered in 5.56 NATO/223 Remington remains the standard for classic AR platform rifles. As some have said, Armalite put the AR in AR15 but Colt made it a household name.  A long history of military and law enforcement use has earned Colt a reputation for building quality ARs and the M4 Carbine continues that tradition. Colt remains committed to offering the highest quality products and proudly presents this Iconic rifle for sale to the US consumer market. The features of this rifle remain the same as the previous LE6920 platform with only the rollmark changing for commonality with current and future builds. The CR6920 Colt  M4 carbie features a 16” chrome lined barrel with a 1;17 twist  and A2 flash hider. A2 fixed front and Magpul flip up rear sights provide a fast, reliable, and accurate sight picture. This rifle comes standard with a 4 position collapsible stock with front and rear sling mounts. Other standard features include a forward assist, brass deflector, and dust cover. A Picatinny rail on the upper receiver provides ample room for your choice of magnified scope or red dot sight. The Colt M4 carbine is both an iconic representation of the original M4 that is ready to go right out of the box and a fantastic starting point for your personally customized AR build.
