    Colt 6721LE...... Hottie or ????

    Well, there's certainly nothing wrong with the quality of this massive Colt Tactical Cannon - ah, oops, Carbine.
    No, my question here is how is this piece perceived in the hive mind over here at this most enlightened of
    all AR sites. I got mine in a trade some time back, and initially had little use for it, but....with a few changes
    she became one of my favorites in the harem! I must say that weight was an issue as was balance, but with
    the balance corrected, the weight was much less noticeable. She is one accurate beast, for sure!

    Best I can tell by a quick set of searches, the 6721 is a flattop with a 16" 1:9 heavy barrel, correct? LINK

    If so, then I'm sure most will agree it's a perfectly serviceable carbine, but that the 1:9 is limiting in that it may exclude some of the heavier grain loads that are top performers, and the heavy barrel is less than ideal in the carbine format. The weight penalty outweighs (ugh, no pun intended) any perceived benefit of the heavy profile for most of us.

    You mention changes; I think any further discussion about how good it is would be lacking if you didn't detail what changes you made, why, and what, if any, issues they corrected. I see something about the balance in your post...did you put on a heavier stock? Replace/reprofile the barrel? Start working out?

    I always liked the flat top on the 6920 and 6720, however I LOVE the 6520 pencil profiled L.W. barrel......so obviously when colt produced a m4 flattop receiver barreled with the 6520 l.w. barrel, I felt it was magic
    Trident, are you referring to the AR720 that Clyde Armory has introduced? The flattop w/ pencil barrel? LINK

    Looks like it should be a good carbine, but I think "hottie" would be a bit exuberant.

    The 6721 is a fat girl with a nice personality. Its reliable, but no fun carrying on a regular basis.

    She's a hottie in western Pa. for sure! Replaced the Lily Po slider and carbine handguards with M4 handies
    and the butt with an A2 unit with all the rifle goodies inside. MIAD grip makes her fun to hold on to, and
    the carry handle has been semi permanently fastened on with my patented knob removing hardware
    upgrade. The butt contains a cleaning kit and the MIAD, an M14 oiler and spare key and cam pin. She is
    definately heavier than stock, but is so well balanced that you just don't "feel" the weight...until you've
    carried her around all day! I'm getting really tight groups, even with 75 grn. loads, so no complaints in
    that dept. I may add a UBR in place of the A2 in the near future, altho I'm told it won't affect the weight
    much, if any. For a carry piece, she will never be a 6520LE, but then, that's what 6520s are for.

    Well, Gee....you hit the nail right on the head! Colt's tactical CANNON. OTOH, if this upper was placed on
    an M4A1 lower, along with a thicker gas tube, you'd have a pretty decent SAW! My 6721 doesn't get
    as much use as it used to, thanks to Mark Westrom's marvelous invention...the Middie!

    It's essentially a 6920 with a heavy barrel. Let's not get carried away, shall we?

    I should also add that I had one a few years ago and would take another in a heartbeat.
