The Colt LE6940 Monolithic Advanced Law Enforcement Carbine, an upgrade of the 6920, have started popping up for sale. The rifle features Colt’s new monolithic upper receiver. This 1-piece receiver is machined from aluminum billet and includes a full length rail.

The LE6940 has a 16.1″ free-floating, barrel, MaTech back-up rear iron sight and gas block mounted front sight. The rifles pictured are semi-automatic, but I am sure Colt will produce a variant with a rock-and-roll switch for law enforcement.

The Colt name does not come cheap, although neither do monolithic receivers, and if you can find one for sale it will probably cost you $2400-$2800. It does come with two 20 round magazines and a sling … if that makes the price easier to swallow.

    I used this rifle in fallujah iraq and fell in love with it. Alot of guys loved the rifle just wanted a heavier caliber. I love the rifle and just wanted better ammo. A 556 with hollow points makes one heck of a mess up close and personal. Anyways i bought my sp6940 for 1260.00 out the door. The pony has earned her reputation and this rifle is no exception. The rifle is sub moa all day long with no malfunctions.
