i have the opp to buy a Colt Defense marked AR,its a 16 in 'C MP" marked bbl, the recvr is also marked match targtet or match competition. thing is, its a flat top and the symbol on the upper looks like the Armalite 'A' but im told its an A for Alcoa forging. Im basically wanting to make sure this isnt a franken gun and get a model number on it so i can find a twist rate etc. i cant recall if it has a bayo lug or not or the flash hider type but any info or pics is appreciated. I did call COLT today and they basically couldnt tell me anything other than they did make a flat top in 16 in... I know im giving limited info but its all i can recall right now and any help is deeply appreciated..thanks

It sounds like a 6731.  Can you post pictures?

i dont have  pics and cant get them till tomorrow and thats if i take the gun. i did find out that its a 1/7 twist and has no bayo lug and is marked 'match target carbine'.  any ideas on value/quality etc??  thanks

My guess is a 6400.
MATCH TARGET
M4 CARBINE

You need to look at your gun and tell us all the writing on it.

That is the only way we can help you.

as i stated, its not yet my gun, its not in MY posession, i simply have the chance to purchase it. i have also  in this thread relayed ALL of the writing on the gun..there is no more than ive already stated!. here goes altogether.

on lower
COLT
Match Target M4 Carbine
5.56 NATO

by selector
Colt Defense
Hartford Conn

on barrel
C  MP
1/7

just lookin for opinions and  a model # with approximate value..thanks

you got the ban  era 6400c. its basically a ban friendly M4

quality is great. as good as a 6920 really. just replace the fixed stock and have the barrel threaded and you got damn near the same thing. minus the useless bayonet lug

I used a 6400c lower as the basis for my M4 SBR. Sold off the upper and replaced  the fixed stock with a Colt collapsible and a 14.5" Colt upper

Thanks guys!! thats  the info i needed. the gun looks brand new and it already has the adj stock on it so half my work is done. I have 3 other Colts but wasnt familiar with this particular model but i do think im gonna go ahead and take it!. thanks for everything

picked up the gun today, gonna change out the muzzle brake monday and change a cpl other things...the lower is marked 223 and the bbl is marked '1/7,  5.56 NATO'...i think i got a good deal and im happy with it. pics later tonite

Another pony rides again , fun times with your new toy ..!

Sweet!! I know you will like it!! and here is my Colts a 6920 and a 6700 I had threaded for a FH. It turns out great
