I have a Colt M16A2 in the older Colt grey. It is currently in a Comando (11.5") setup, but I want to replace the upper with a 6921 HB 10" barrel assy and a Colt M4 upper (with M4 feedramps). I am trying to find a Colt M4 upper (A2) in the older Colt grey for this project. Anyone know where to look or purchase one?

Semper Fi,

I've reread your post a few times, and you are still losing me. Did you cut your 6921 barrel down? Are you looking for an A2 upper with M4 feedramps?

If I'm reading it right, he wants a 6921 entry barrel on an M4 upper (with A2 sights), that will match the color of his M16 lower. I think one would have to refinish the receiver in something like Norrells Moly Resin for that though, as M4 feedramps are kind of new(relatively speaking), so probably wouldn't be found on an older Colt grey receiver.

Correct. I guess I could just find a grey Colt A2 upper and have the feedramps installed if worse came to worse.

Try the EE, the upper you are looking for can be found off a Colt 6520, but it would still need to be refinished.

Taken from the Norrells website....

GRAYISH-BLACK Flat
Dark gray-black coloration with a flat appearance. This duplicates the appearance of the early original Colt AR-15/M-16 finish. This is the same product that is purchased from us by the U.S. Military to refinish Colt M-16's.



Here is a picture that may help.

Thanks for the info. Mine is actually a little lighter grey than that. I may get a black M4 upper and refinish or a grey A2 upper and install M4 ramps.

If you are grinding through the surface, you are cutting through the anodizing, which is what gives it its hard coating and protection. Just something to think about, I've cut a few, but I'll end up replacing them as I get time and funds.

I have two gray Colt M4 uppers, complete with M4 stamp and feedramps. They're sitting on a pair of preban lowers. I am certain the finish is Colt factory, the match is nearly perfect. I've had them for quite a while and don't remember where I got them.

I don't recall seeing many others over the years, but I believe they're out there. You might try a WTB ad on the EE and maybe also over on Sturmgewehr or Subguns.

The options I would consider:

First, you can buy a Colt M4 upper that was factory produced in gray. ChrisM in Texas often has these: clm4@REMOVETHISev1.net. Then add your own barrel.

Second, you could buy a complete Colt M4 upper in the current black finish and send it off to Victor at US Anodizing to have the upper receiver re-anodized in Colt Gray. Victor does outstanding work. He re-anodized my Colt M16 lower that had been previously refinished in Norrell's molycoat. His work is outstanding and he can perfectly match Colt gray factory anodizing.

Third, and probably the best option is to buy one of the M4A2 uppers from Fidelis Firearms and have the barrel chopped by ADCO
