I was at a gun show today and one of the vendors had a stripped A3 upper and stated it was factory Colt. He had it marked $200 but told me he has some room on it. I have a Colt rifle and want to build a midlength upper for it and would prefer to stick with the Colt receiver as well as keep the current upper as is. I looked for markings, but am not 100% clear on what markings are correct and such. There is a C on the side of the upper right under the rail on top and then a funny looking symbol to the right of it that looks like an A and an F squeezed together (i think).

Can anyone show me the correct pics of the proof markings it should have one it etc and tell me a price? I know I have seen pics before showing what it should look like etc. If it is what he says it is and I can verify it I will go back and make him an offer on it tomorrow as I am going back anyways.

Any help? I would look at mine but I am out of state for business and do not have my rifle or anything to compare it to with me. Thanks in advance...

Also, as a bonus could you tell me where I could buy such a thing if I do not get the one at the gun show.

Look on the front of the receiver, does it have an 'M4' at the front of the rail portion? It is most likely a Colt from the markings described.

I'd go to S.A.W. for the receiver if I were you, $200 is ridiculous.

I appreciate the input and the link...

however, according to the prices listed on that website the $200 wouldnt be ridiculous because that is how much they are there. He also told me he had some ROOM on the receiver and actually qouted me $180...which I would offer him less than that still. Prolly $150 and see what happens.

Any other input? Know where I can look at pics? I did not notice an M4 stamped on it or anything. Also, the t marks on the top were not white or whatever, they were engraved into the rail. Is that accurate for Colt?

You can get a complete new Colt's M4 upper receiver for $165.00 from Brownells or check here on the Equipment Exchange. You can get an LMT upper receiver from one of the vendors on the EE for less and it will be just as good IMHO.

Good luck!

+1 for the EE.  I bought one last year from another ARFcommer for a very reasonable price.

The C and AF marks are Colt's, Alcoa Forge. The A3 receiver will not have M4 feed ramps, nor M4 on the front above the gastube cloverleaf.


Good luck...
