The Colt M4 Carbine 6920 is a semi-automatic version of the Colt M4 Carbine issued to the U.S. Armed Services.  Other than having a semi-automatic receiver, and trigger group, and a 1.6” longer barrel; it is the same gun as produced for the military.

The M4 Carbine is the latest version of the M-16 used by the U.S. Military.  It has all of the M16A2 features with a shorter, 14.5” barrel, collapsible stock, and flat top upper receiver.  Other than some Armalite test guns, Colt was the original manufacturer of the M-16.  Colt was also the exclusive Manufacturer of the M4 Carbine for the U.S. Military from 1994 to 2009.  Since 2009, both Colt and FN (Fabrique Nationale) have manufactured M4 Carbines for the U.S. Military.  

Since they are the actual military manufacturer, certain civilian versions of the Colt (and FN) are true mil spec.  The LE 6920 is a semi-automatic version of the M4 originally sold to law enforcement and the closest copy a civilian can get of a military M4.  Though called a law enforcement model, with LE prefixed serial numbers, this model can be purchased by civilians in many states.   Colt makes several versions of the M4 and AR-15 (Semi-automatic M16) but the 6920 is the closest to the military issue guns.

Being true mil spec the Colts have several difference from normal M4 Carbine clones (except FN and some Stag Arms).  These differences include:

  • Staked stock buffer tubes and bolt carrier keys.
  • Chrome lined, 1 in 7 twist barrel with M4 Carbine feed ramps.
  • Full Auto Bolt Carrier.
  • Proof tested and magnetic particle inspected bolt groups.
  • Inspection markings indicating milspec quality tests for various components.
  • Double shielded handgaurds.
  • Colt Rollmarks and barrel markings.

Being built to true military specifications means that the Colts tend to be more a little more reliable and accurate than most of the clones costing less than $2,000.  Colts are also the most collectible brand of firearm and thus, the Colts tend to go up in value over time, if well cared for.

The M4 are very popular due to their modularity.  With a rail system to replace the front handgaurds, in addition to the primary and backup sights; lasers, weapons lights, bipods and hand grips can be fitted.   The rail system on the receiver allow optics ranging from Aimpoint Red Dots, to Eotech Holographic Red Dots, to Trigicon ACOGs, and standard scopes to be fitted.  This has revolutionized combat.  Some may argue that the M4 lacks takedown power, but with the latest optics and other devices, the percentage of hits on enemy targets in combat has increased dramatically, with even headshots being common past 100 yards.
