    Default Offical Colt LE6940CK Upper Assembly for Commercial Sale---Pix

    For the first time as long as I can remember, Colt has released complete upper for sale in the commercial market. This is a monumental step on colt's part as to their commitment to the Civilian market.

    Available for purchase are Colt LE 6940CK and LE6920CK, the CK part of the part number denotes this as an upper assembly only.

    There is no what so ever difference between the complete rifle or the upper assembly. CK might stand for Component Knockdown.

    I recently picked up a Colt LE6940 for my California registered Colt lower.

    Interestingly, my lower has a small pivot pin hole and mate to the mil-spec small pivot pin of the Colt upper perfectly. Another step for Colt is to merge the mil-spec aspect of the Colt defense guns to the commercial market offers.








    The silver tab below the rail are the detent for the lower rail take down catch.


    Not something you can do with your finger unless you have the finger of a small child, but a simple as a bullet tip will do the job just fine.


    Detent catch


    Gov't profile 16.1inch M4 barrel, unlike the LMT MRP, the Colt 6940 will take a standard mil-spec barrel. with the right tool, you can actually drop a 10.5inch barrel into the platform and make it into a modern CQB-R


    The 16.1inch M4 barrel are standard mil-spec affair, chrome lined, M4 feed ramp, MP tested, and 1:7 twist to best fit ammunition from 55gr to 77gr.








    Cast flip up front sight gas block


    Notice the hole opening, this was originally design for the model 1020 piston carbine, which was reveal during the 2006 Shot show. Although the piston is still an in house project and the engineering team took the basic 1020 design and came up with the LE6940. the hole is mostly likely left for the piston assembly in case for a future release. few CNC steps and this can be a piston ready gas block.


    The front sight kept the usual M16 front sight blade profile.




    The detent for the flip up front sight are friction lock with no extra button to push for deployment. This sight has a pretty heavy spring detent so it will not be easily knock down during deployment.




    Like the Colt LE6940 carbine, the LE6940CK comes with the US Army approved Matech rear sight.


    Bolt carrier group are the proper M16 affair, this give the gun better felt recoil and timing even during semi auto fire.


    I drop the LE6940CK right on top of my California Registered COlt AR15 HBAR lower. added the components below
    LMT SOPMOD stock with Colt buffer tube and H2 buffer
    MidWest Ind. SPLP rear BUIS
    ADM EOTech quick release Riser
    EOTech XPS-3
    Surefire M900 Scout with the latest 120 Lumen TIR lamp assembly
    TangoDown QD vertical grip
    TangoDown BG16 pistol grip
    TangoDown rail panels


    This will effectively become my primary carbine for the foreseeable future replacing my LMT MRP CQB.


    Compare to my LMT MRP, so far the gun feels lighter, thus point from target to target faster, the lower to upper are nice and tight, and the balance is superb. I plan on attending the Surefire Low light carbine operator course this weekend with Bill Murphy and will give this gun a good test.


    My new Colt LE6940CK compare to my ole trusty LMT MRP CQB.

    Aah. I was wondering how the EOTech XPS would look like on top of a LaRue EOTech riser mount, I see you have one on an American Defense riser mount. Nice. Thanks for the pics.

    Anything special I have to do to own one of these in California Lee? I know that the lower needs to have at least a bullet button, but what about uppers? I'm tired of not having an AR platform in Cali.

    Buy an Off The List Lower (OLL) and add a bullet button to it, you will be good to go with whatever upper or a nice Colt 6940 on top of it.

    Is that a true Monolithic upper? Or just a permanently attached handguard?
