The nation’s primary manufacturer of the AR-15 series of rifles introduced the LE 6940 carbine for the 2009 law enforcement market. The gun that I saw was semi-automatic, but I am sure that a full auto version is available for qualified buyers. The gun is a traditional direct gas impingement gun (a Colt representative at the show told me that they have no plans to make a gas piston gun) in an M4 carbine configuration with a difference.
The receiver and top half of the fore-end consist of a one-piece, free-floating barrel assembly, which has proven to increase accuracy. To gain access to the barrel, the lower section of the railed fore-end can be removed by pulling several pins. The fore-end offers classic Picatinny rails for the addition of needed accessories, including side mounted sling swivels. The gas block doubles as a flip-up front sight so that it does not “clutter” the sight picture of any optics added to the top of the receiver. The iron sights that were standard on the gun I saw were simple and robust.
