The heart of this LE6920 is a 4150 CMV steel barrel marked “C MP 5.56 NATO 1/7,” chrome-lined for durability and corrosion resistance. The M4 profile keeps weight balanced while retaining bayonet lug, carbine-length gas system, and M4 feed ramps for reliable cycling.
The direct-impingement action runs smoothly with a standard safe/fire selector, and the AR-15 platform ensures broad parts compatibility. A collapsible, six-position stock pairs with the A2 pistol grip to give a 10-inch length of pull that fits most shooters.
Two-piece ribbed polymer handguards provide a secure grasp and retain the classic look, while the threaded muzzle wears a pinned flash suppressor that both meets 16-inch minimum length requirements and reduces visible signature.
Colt’s LE-prefix serial numbers indicate post-2013 civilian production, preserving authentic M4 styling in a rifle made in the United States. With its proven design and included PMAGs, this carbine is ready for range duty right out of the box.
