    Yes.

    But it's sort of like putting a Dodge Viper engine in a Kia.

    I know it's best to say nothing if I can't say something nice and all that. :)

    Have 2 DPMS heavy barrels, both are excellent shooters. Colt would be about number 4 on my list.

    After some thought and reading this post of yours I have a suggestion that if it were me, I would do.

    You already have a good upper, the Colt Match Target. It's a good shooting 20" barrel. Going to a longer barrel isn't going to help much at all if any with accuracy. Going from a 20" to even a 26" barrel will only up the FPS by about 120FPS. IMO the longer barrel will add weight more than anything.

    You want the option to shoot iron sights and use a scope. Correct?

    I would buy a flat top upper, a rear BUIS (back up iron sight), a scope, and a quick detachable mount for the scope. And a free float forearm would be a nice addition but not necessary unless you are serious about consistent tight group accuracy.

    This costs far less than buying a complete upper and will allow to to go from irons to scope and back to irons easier and faster and you can make the change in the field.

    Here's a link to an interesting discussion on barrel length than you might want to read.
    http://www.ar15.com/forums/topic.html?b=3&f=118&t=528841

    Some example pics...

    This one of mine isn't a 20" but it has a flat top, BUIS, Scope with QD mount. NOTE: Old pic, that ARMS QD mount on the ACOG scope was replaced with a far better one made by LaRue Tactical. A quality QD scope mount will hold your zero when you reattach your scope.

    In about 10 seconds I can remove the scope and flip up the BUIS and shoot irons.

    TROY makes the best BUIS in my opinion.

    I don't use irons on my 20" Armalite target AR, I just swap between an ACOG and a Weaver 4-16 scope on it. The 20" match barrel is very accurate and I see no reason at all to ever go with a longer one.

    You will need the following, you can go cheaper but I'm showing what I would go with for an example.

    Flat top upper $99.00
    http://www.bravocompanyusa.com/Upper-Receiver-Assembly-Flat-Top-p/flat%20top%20upper1.htm

    TROY rear BUIS $119.00
    http://www.bravocompanyusa.com/Troy-Folding-Battle-Sight-REAR-p/troy%20rear%20sight%20-%20rear.htm

    LaRue scope mount. $195.00. Yes it's expensive but it's the best made IMO. You can find others for less that will also work fine. I still need to buy another one but can't seem to ever have the money for it right now.

    And you should have a receiver block and barrel nut wrench to swap the uppers. Good to have these tools around anyway.

    Upper receiver block $35.00
    http://www.midwayusa.com/viewProduct/default.aspx?productNumber=593549

    Barrel nut wrenches run around $25 - $35.

    Not hard to swap out the uppers and I think you will be happier with what you have in the end.

    I hope this helps give you another idea as to what you can do. Good luck.
