The upper, made from a CNC-machined 7075-T6 aluminum forging, features integral top and side Picatinny rails extending forward just to the rear of the gas block. Recesses for quick-detachable sling swivels are located on both side rails. The bottom rail is a separate piece that can be detached for cleaning or installation of under-barrel accessories. All rail sections have numbered slots for repeatable installation of devices.

The LE6940 has extensive parts commonality with the M4, sharing the barrel’s chrome-lining, four-position collapsible stock, and birdcage-style flash hider. Also present are the familiar shell deflector, ejection port cover and forward assist. The LE6940’s bolt, carrier and trigger mechanism also follow the proven AR-15 pattern, as do the controls on the lower receiver: magazine release, reversible safety and bolt release. Like all current Colt-produced rifles, the LE6940 uses 0.154-inch-diameter hammer and trigger pins.

The 1:7-inch twist of the barrel and 5.56x45 mm NATO chamber allow the use of 55-grain, 62-grain and 77-grain ammunition. The M4-style barrel measures 0.750 inches at the gas block, but decreases to 0.640 inches under the handguard, and incorporates the M4-style step. Barrel attachment is by way of an improved barrel nut that reportedly offers greater strength.
