Just got in my brand new Colt M5 this morning from my FFL and noticed several differences in it and every one I’ve seen online so far. My lower is marked “M5 Carbine” instead of just M5. My upper doesn’t have the little place that others do where the patent number went on the 6940. My lower also doesn’t have the stupid third pin deterrent extra material in the lower. Mine is fully cut out like a normal M4. From what I can tell most everything else is the same. Does anyone know the reasons for my differences? My serial number is within 5 digits of the one MAC tested and his was marked M5 and had the extra material in the lower.

Colt probably took a lower originally intended for military sale and used it for a civilian carbine.
Colt put out some weird stuff sometimes… years ago I remember a 6920 sold with AUTO marking sanitized… another one with a FA hammer installed..

I’ve seen the M5 Carbine marking only on early NFA demo guns

@Brock51 what does your selector marking say.  Safe/semi or safe/fire?

That is interesting how the FCG pocket is cut. I have not seen that before. Not quite the "normal" AR15 cut, not a complete fully cut out pocket either

Yeah very strange, left side is M16 cut and right side is a AR15 cut

They have 4 left it says and are the best price anywhere.

[#14]
Correction, I just went and checked they only have 2 left! I’m thinking they’ve just sat on these for a long time and these were some of the first iterations of it.

I think you’re right.
One of the first user here receiving his M5 had SN 6510xx or 6511xx… latest units are 6522xx range (see the 10+ pages thread on this board).
Also you have a gen1 BHO lever on the right side.

Your is definitely an early production sample.

Is this a solid improvement  over the M4?

The way I see it yes.
If you want to issue an upgraded carbine out of the box to troops/officers without dealing with installing aftermarket parts, seems like a good start imho.
You also get a stronger upper receiver & ambi lower if that matters..

Buying a 6920 for under 1k then spending time & money to replace GB, HG, etc doesn’t make sense anymore in 2025.

Well checking the serial number of it on Colt.com is coming up as no results found. I’ve seen serial numbers within 10 of mine that don’t have any of the same features.

I went ahead and ordered one.  Even if the one I get is just marked "M5", the price is certainly right.  Nobody else is even close.  FYI, both of my M5 SBR's (10.3" and 11.5") are marked "M5" only.

This is another showing of Colt continues doing what they do the best - put out things of no logical pattern. In the end, it functions as intended, marking and machining lower FCG pocket difference don't matter.

Can't find it there - guessing its sold out. :-/

Arms Unlimited has them for $1299, only $100 more

Yea they all sold after I made this post pretty quick.

Please update us when it comes in and let me know if it’s the same as mine. Are there no Colt workers in this forum?

The one I ordered from Bereli also came with the M5 CARBINE model designation on the receiver.

Nice! Glad to see the other ones from Bereli have the M5 Carbine markings. Another interesting thing about mine is it isn’t in Colts serial number lookup on their site. It shows it not to be in their database.

That’s not unusual for Colts serial number lookup.  It’s almost like it was some summer interns “keep busy” project.  They got a few loaded in and when they left that was it.

What am I missing?

Ambi mag release and curved trigger guard.

Does it do anything else cool?

They have a true free float barrel due to the proprietary upper they use, plus the have the cool bulging where the trigger pins are for whatever reason. But really it’s just Colt’s newest weapon system they released. It’s actually doing very well with contracts around the world thanks to CZ influence. It’s being used in war by Ukraine, used by Russia with ones they’ve picked up, used by Israel in war, and other random militaries around the world like Georgia, Romania, Chile, Thailand, and several others I can’t think of off the top of my head.

I got one of the 6940 guns when they appeared. Nice enough gun, but wasn’t unique to my needs, so sold it off.

The 6940 required a one-off wrench of some sort to remove the barrel. Not that I was ever gonna shoot it enough to wear out the barrel.

Does the M5 barrel assembly require a special one-off wrench to service it?

They use the same barrel nut and proprietary wrench.

A significant difference between the 6940 series and the M5 series is that the M5 series rifles are much less front heavy.

M5, 6940, IAR all have a proprietary barrel extension as well.
