I did a quick side-by-side and was wondering, besides the lack of a bayonet lug on the MT, what are the differences?

If I remember correctly the MT6400C has a fixed buttstock and a muzzle brake instead of flash suppressor to comply with ban requirements. The rollmarks, of course are different as well.
Looking at the pictures from the Colt web sights, it would appear the muzzles devices are different. I wonder what differences there are in components, if any. Ultimately, I'm trying to decide which one to order.

MT6400C

Right now it really depends on what you can find. If you are offered both and at the same price, go with the 9620. You may be able to find a better deal on the 6400 though and if you're going to change out the stock and/or muzzle device anyway you might as well go with the cheaper model.
The 6400c comes with the cut down, neutered style bolt carrier whereas the 6920 will come with an M16 carrier.
Interesting, I wasn't aware of that.Quote:

Good info, thanks!
get the 6920
The 6400 will have a stock that will not adjust. It would have to be completely replaced (approx $80 - $175), depending on the mfg.
The 6400 will have that silly muzzle devise. To replace would cost $50-$100
The 6400 will not have a regular size mag (value $15)
The 6400 will not have the M16 carrier.
The 6400 will have lower resale value.
If the features listed above don't mean much for your use, than the 6400 is a high quality option.
I have owned both models. My understanding is the last batch of MT6400s came with a M16 bolt carrier. The switchover was Colt wide, older 6920s didn't have the M16 carriers, IIRC. I didn't think Colt made the Match Target series any more, are they still producing 6400s?
The difference is the rollmarks, pinned muzzle brake versus threaded on flashhider, fixed faux collapsible stock versus real collapsible, bayonet lug missing on the 6400.
I'd get the 6920 unless you are legally bound to get 6400, or it costs enough less that de-bannifying it would be less than getting a 6920. They do have "M4 Carbine" rollmarks, which are kind of cool, but I didn't like the "Match Target".
I bought a 6400C back during the stupid AW ban and that thing still runs like a Singer sewing machine!! It is truly a fine "almost-true Colt" M4 for those that think Colt is G-D. Mine came with that ridiculous muzzle brake too. In my opinion, that is the number one reason not to get one now that you have the choice between it and a 6920.
That said, I had the brake removed, a phantom put in its place and added a Magpul CTR and I will never get rid of that rifle. If I could have a bought a 6920 for just a couple $100 more back then I would've though.
Does the 6400 come 1/9 barrel and the 6920 come with a 1/7?
Nope. My 6400MT has a 1:7" twist.Quote:

A big plus one to that. The last I heard, the MT line was killed off in early 2005.Quote:

Maybe a Collectable in the future, Since it's not made anymore...
:D
Let's hope. ;) Good point - could removing the crappy brake diminish the value of the rifle since it's not in its original configuration. . . . not that it's being sold in my lifetime but it'd be nice to know.Quote:

I don't believe the Match Target line has been discontinued, but they are generally unavailable right now. Like seemingly everything Colt makes, they manufacture their rifles and carbines in batches. Nothing from the MT line has been made since March, IIRC, and isn't likely to me made again until sometime in early '07.

6920's are vaporware. If you can find one, get it! I did however manage to pick up a 6721 to stock.
C4
Lawmens Safety supply in Raleigh,N.C. # 919-779-6141 had some new 6920's last week. Might be a source if anyone is still looking.
If you live in a ban state then the MT6400C is your only choice, it is a fine rifle (except for the retarded brake).
If you live in a free state then I would look until you find a 6920.
Mine use to be an MT
It was heavy!!! and LOUD!!!!
Sorry to use the paddles and bring an old thread back to life but I thought it was better than adding a new one since my question is in this one.
The only 6920 listed in Colts site right now is a LE6920,
Since I would only be able to get a MT6400C, am I better off getting a Bushmaster M4A3 since I can pay the tax of 200 and get the 14.5 inch model or get the 16.1, And the BM has the fully lined chrome barel and chamber.
Also what about the 6920 being stated as to be chambered in 5.56, and the 6400 in .223...
BTW, it would only be a home defense weapon and will shot at the ole cabin maybe 2-3 times a month. But I was ADD advanced in high-school so I can and would prefer to just spend a little more and get the best.
Would honestly like to have the closet rendition of an M4.
Thanks Guys,

Thanks,
I am trying to figure out what the deal is in NC about the 14.5" barrel stuff.
I found a used MT6400C in a local store that a guy is selling but he hasn't caled me back yet.
It was made in 2004 and has a nice ACE skeleton stock full size and it fells so good. This is going to be my first AR-15 purchase and I think it has what I wan't. Mostly the 1:7 barrel to shoot the heavier grain ammunition. I believe the lady at Colt yesterday told me the barrel and chamber are chrome lined also. Oh and BTW, I loved the trigger...It would not move until it broke, at @ 3.5 lbs I am guessing, and I was impressed, reminded me of a good 1911 you know.
I got a MT6400c during the ban days. When the ban died, I replaced the fixed stock with a Vltor & I sent the upper to ADCO to have barrel threaded so I could add a Flash Suppressor & get rid of that muzzle brake. I have a Bushmaster & never had any problems with it, but the Colt is my favorite. My MT6400C has a chrome-lined chamber & bore and it has 5.56mm chamber, not .223, 1/7 twist
Why can't you get a LE6920? My friend got one couple weeks ago. I would get a LE6920 if I had the choice.
I am awaiting a call back from ATF in Charlotte for the "Official" info on that.
I would prefer the 6920 as I think the 6400 I am looking at is .223, The barrel wouldn't be different from the lower would it.
I need to call the range and have them check for me, I would rather have the LE6920 b/c of it's designation as 5.56, even on Colts site the MT6400c is labeled as .223.
Why are you worried about a 14.5" barrel on a 6920?:confused:
The 6921 is the 14.5" barrel version.
It's not that, sorry for the confusion...
I can't get a straight asnwer from the local shops about me, a Civilian, purchasing a 6920 which from Colt is marked LE Gov't use...
Even the lady at ATF in Charlotte told me she would have to call me back. I am aware of the 200 registration/tax/fee for a barrel under 16" but with the markings on the rifle I can't get a straight answer yet. We have a grat class III dealwr but he is ata gun show and I can't reach him until next week.
Colt told me yesterday that they keep those marking for the 7 states that kind of have their own state laws that are very similar to the ban laws. And that I should be able to buy the LE6920 which is the one I want.
Any clarrification from anybody who works for a dealer would be awesome, I have been reading off of ar15.com for almost 3-4 hours in the past 2 days...
If you can buy a new production Bushmaster you can buy a 6920. The markings on the receiver are irrelevent.
I did, thanks...
Talked with a smaller but down-home awesome one at lunch,
He set me straight, even got out his book and made three or four calls looking to find me a supplier with a 6920, he found 7 6921, which I might conside b/c I can't imagine getting ahold of the grenade launcher but who knows.
Then he told me that if I can get the 2yd ol Match Target m4 for the price I told him, then get IT.
he told me he sold a 10 yr old barely shot 6400 for 200 more then what I am getting this one for.
I like honest folks...:cool:
Anyone got any pics of the differences,
I can access the pic from Bushy web-site for the A3M4 parts diagram but don't know what the 6400 part would look like.

unshrouded older Bushmaster AR15 carrier, RRA 'enhanced' AR15 carrier, Colt M16 carrier.

The MT carrier is like one of these below.
Here's two 1/2 circle Colt carriers.
My 3gun rifles carrier, it's a Colt 1/2 circle unshrouded carrier. It's light for less recoil. The barrel is a midlength and I use an Enidine buffer w/standard power CAR buffer spring. Less moving mass = less felt recoil & muzzle lift.

My wifes 3gun'ish rifle Colt 1/2 carrier, shrouded firing pin.
http://img.photobucket.com/albums/v4...rdwrail007.jpg
I believe the newest ones I've seen from Colt in their commercial rifles were shrouded but still 1/2 circle. Yes, the 6920 has a M16 carrier.
Commercial Colt is kinda weird, they do a combination of things so that you can't add an auto sear or M16 FCG parts and mil-spec sized pinned uppers on to their lowers. These things are different (larger) hammer and trigger pins, hardened block above the safety, and large pivot pin uppers.
If you want an M16 carrier you can buy one and just add it to a 6400 if you don't have the lower receiver block in it, and either sell or just use the 6400s carrier in another rifle build. Some full circle carriers will still work even with the block in the lower. The RRA has a bit longer section at the tail and may not fit. If you do run a M16 carrier it's wise to get a non-notched AR15 hammer (these are available from DPMS).
