Understandable. The true value of these primarily resides with collectors.

I picked my carbine up today.

The following parts are serial numbered on my carbine.

Serial numbered upper receiver

Thank you sir.

One new thing I forgot to mention was the R
on the barrel. I have seen many R's over the years. This is the first time I have seen one underlined.

I saw these in my gun shop in Budapest.

They are nice looking and are selling pretty fast.

Thanks for sharing
That confirmed my idea of the bolt being serialized.

ETA
Is the barrel still CL?

Any chance you could measure the chamber if it’s really 223?
Surplus 556 ammo is showing up over here finally (the head stamp gets machined off so it magically become 223)

The barrel is chrome lined.

I currently don't have anything to measure the chamber unfortunately. I really need to correct that.

All the MT series came with a 223 labeled box but they were 5.56

Colt wouldn’t be the first to mark stuff as 223 just to comply with our stupid law but still making true 556 guns

I called Sig Sauer 3X about my 7.62 Patrol Rifle, they assured me all 3X it was chambered in 7.62, but its not, its 308. Gauges don't lie. Barrel stamped 7.62, marked 7.62 on box, 7.62 on Manual, but chamber is at 308.

Good reasons for doing that, then deny doing that lol!.

Until a chamber gauge is actually inserted in this Euro Colt, I would still bet its 5.56 no matter what people at Colt are stating. But thats just my guess.

I have the chamber gauge, just not the Euro Colt rifle, guess I need to order the Colt. Much easier for someone else already with the rifle to order the gauge, not even very expensive.

I wouldn't want the rifle if it is really .223. Thus the reason I haven't bought one, hoping someone with a M Guns Gauge would check it first, then we will know for sure.

.223/5.56? Gage

This gage tells you if you have a chamber that is 5.56 NATO (or larger), or something shorter/smaller.

The gage looks a lot like a headspace gage but it does not gage headspace. It comes with its own rod which you thread into the tapped hole in the back of the gage. Unload and open your rifle, pull the bolt group, make sure the chamber is clean so there is no false reading, and drop the gage in. If the gage's shoulder "clinks" off on the shoulder of the chamber and the gage drops or pulls free without sticking or resistance, you have a chamber that is 5.56 NATO or larger. If the gage goes in and wants to stick, as in, you let it in and it pulls with a little resistance, or you try and turn it but it does not turn freely, you are short of 5.56 NATO and probably have a .223 chamber. You can color it up with a Sharpie, put it in and spin it (clockwise) to observe where it's contacting the chamber first.

Note that the gage will also stick in a .223 Wylde chamber since the Wylde's freebore is smaller in diameter than the 5.56 NATO's. It's my opinion that the Wylde chamber ought to be OK with 5.56 NATO ammo, but I have not delved into this scientifically. I don't own anything with the Wylde chamber, so I have no first-hand experience with it. The smaller freebore, I suppose, would make it more crud-sensitive.

The newly designed (3/15) handle acts as a case for the gage, preventing loss and damage.

Probing either a .223 SAAMI or .223 Wylde chamber with this gage will not harm the chamber unless you decide to really try by hammering it in. Don't do that.

Price is $65, add $10 for Priority Mail, or $5 for first class.

I have gauges. I wlll gauge mine this morning.

You have the M Guns 5.56 Gauge? Awesome, look forward to your findings.

What did the gauge say?

Well, I have apparently lost my 5.56 gauges. The only gauge I could find was a .223 field gauge. Bolt would not close.

I have some new gauges on the way.

Thats not what you need, you need the M Guns chamber gauge I posted about earlier in thread.

Right. I ordered that too.

Now I am excited as you will get that M Guns gauge way before I get my gun. If its a true .223 chamber wonder if I can refuse the rifle before the transfer lol?

Sit on the Euro carbine for a little while at least. Less than 400 were shipped. They will be worth some money.

I am tempted to add one to my collection, I would probably never shoot it as I have other 6920 variants I can shoot, so maybe the .223 chamber wouldn't really bother me as much as I thought. It would stay in the safe and keep my Mexican 6920 company.

I picked mine up today. I’m going to try get it out and take a look later tonight.

They don't appear to be selling well, over 240 still left if the inventory is correct.

I tried reaching out to a few members here………if they weren’t happy.  Crickets.

the ones I got looked great.

Kinda funny you ask about that…..happy….. well mine came a bunch of scratches on the barrel by the muzzle where the Colt assembly monkey’s wrench slipped off the flash hider.  I’m going to have to touch that up or keep it well oiled. It also has the usual marring on the receiver, which is expected with colt.  So everyone else is safe, I probably got the worse of the bunch.

Mine arrived as expected.  I didnt do a thorough exam but I did remove it from the box and bag.  Lots of oil, looked good, put it back in the box and bag and put away.  Uneventful.

Still curious about gauging the chamber

The bolt carrier marking is sexy AF and my favorite detail, I wish all Colts were marked similar.

So I called Colt yesterday and spoke with a new customer service rep that didn’t know much

I told her about the Colt Euro model and provided my serial number.   I explained that I thought this was a European contract overrun and curious if she knew anything about the circumstances.   She did not know anything about the guns.  

I then asked about it being stamped .223 but in the past, .223 guns could shoot 5.56.   She didn’t have an answer.


I asked for a manager to call me and they haven’t.


Update……I called back and spoke to the same lady again lol.  She apologized profusely.   Said she just started in November and is learning everyday.  Said she spoke with her director and will get an answer on the chamber and potentially an answer on why this euro edition was made.  


I’ll keep you all posted

Colt just called me back.   .223 chamber only……………

……yes. That is what the rifle says.

Don’t be that guy.    Historically, colt marked .223 rifles had 5.56 chambers.   So knock it off

Noted in the OP here, also post 42 on first page.

Steyr does the same with their AUG.. theyre marked 223 but are actually 5.56.
Same for the VHS Hellion and even the CZ Bren 2 if I’m not mistaken.

Gee…..thanks for your contribution

Sure, you as well.

Right but what are the barrels marked? That's what really matters on AR15's at least, I'm not super familiar with the AUG or Helion.

Mine was a duel question.  Not just chambering, but what country or entity was this destined for.  While I had them on the line, I asked chambering.   Just go away man.  You think you are funny

I'll stick around until someone gauges one and reports the actual data here.

I'm sure a couple more will check in with their recount of their conversation with some rando at Colt's and restate the obvious.

Very nice!  Thank you for posting it.

The SPORTER (blue label / "tweeners" from 1989 to 1994) had lowers marked 223 but barrels marked 5.56.

I just checked and AU still has 235 in stock.  They’re not selling fast.  I wonder if the 223 chamber is the reason.

Of the 3 I named I only own the AUG. I’ve only saw pics of the Bren and Hellion.
For the Hellion there’s a similar thread on the Bullpup board.

The AUG Barrel is marked 223 but it’s acutually 5.56
One of my Colt had the NATO marking sanitized with multiple XXX.
My other surplus gun a M16A1 and Galil SAR converted to semiauto.. the barrels are unmarked but the importer added the 223R..

It’s just a matter of being politically correct.. that’s why I don’t trust a CS guy.
If theyre in fact 223 then I will hurry up and buy a 556 socom barrel this weekend

I was ready to buy, but after finding out about the possible 223 chamber I put it on hold. I am glad I did as the Candian Colt deal came up and it was higher up on my list of things to acquire.

Is the .223 CIP spec the same as the .223 saami spec?  From what I see the CIP spec states a higher pressure than Saami.

Will a .223 Saami spec chamber that we are used to even pass a .223 CIP spec?

Forgive me if this is a stupid question.........

Is the novelty behind these guns the stamped barrel and BCG with the serial numbers (specifically)?

Did you even bother to read the first few posts?

Try this

Any updates on the chamber type?

deleted

So, after an ordering snafu that was my fault, my chamber gage arrived from Ned Christensen's (M-Guns).

Here is the instruction sheet with the gage laying on the left side. Attached File


The key take away from the instruction sheet is:

"drop the gage in. If the gage's shoulder "clinks" off the shoulder of the chamber and the gage drops or pulls free without sticking or resistance, you have a chamber that is 5.56mm NATO.

If the gage goes in and wants to stick, as in, you let it in and it pulls with a little resistance,  or you try to and turn itbut it doesn't turn freely, you are short of 5.56 NATO and probably have a .223 chamber."

Here is the business end of the gage.

This image is the gage being dropped by gravity into the chamber vertically.
Attached File


This last image is me holding the upper receiver upside down with the gage remaining in the chamber unaided by me.
Attached File


The reasonable assumption to draw from this is that the chamber is .223 since a 5.56mm specification gage fits tightly and does not drop free unaided.

Thank you sir.
