I was looking through Arms Unlimited's website and found a Colt LE6930CK upper half. It is listed as having a 10.3" barrel and quad rail. I don't recall ever seeing a LE6930, so I searched the internet. I didn't find anything other than perhaps some typing mistakes. Is this some made-up thing by Arms Unlimited or is it an actual unique offering from them that you can't get anywhere else?

Wonder if that's the same Colt branded quadie that was on the recent batch of Euro 6920s.
It’s definitely not a KAC rail, nor a copy.Quote:

If a person is going down to 10.3" not sure why they'd want anything else besides a free float mono rail. That was the main attraction of the 6945 for me. If we are doing A2 front sights and rails, I'd rather go 11.5."
And yes it seems like ArmsUnlimited has cobbled together more than a few custom Colts.
This is the way..Quote:

I sent an email to Arms Unlimited asking them if they installed the quad rail or if it came that way from the factory and I also asked if any of the parts are serialized. They replied "From the description it will come just like the picture directly from Colt. I do not see that anything is serialized on it either."
I've gone 14.5 all the way lately. 10.5s and the like are too friggin obnoxious, and adding a can is just as awful.Quote:

Agree, I own that Euro 14.5 and that quad rail is identical. The rest of the upper is Colt standard parts.Quote:

The biggest difference is 4" of barrel is heavier than 4" of suppressor. Even things like a SOCCOM Mini, which are hardly the quietest thing in the world make a huge difference. The only thing 10.3 and 11.5 don't do very well is accuracy at distance, but that isn't really what they were designed for.
I recently got a 16" 6920, and it's a good gun. But I already had stamps on some lowers, and I just grew out of the impracticality of 10.3-11.5". So I put some 14.5s on them.Quote:

For me the 10.3 / 11.5 ARs finally got small enough and light enough and suppressors for them finally became effective enough to fill the role of the MP5 and similar SMGs.Quote:

No. It's too loud and concussive unsuppressed. And suppressors are insane on a gun that short. Too much pressure to try to tame.Quote:

Exactly. I used to be all about the 10.5. Then I was 11.5 city. Now that I've grown to hate suppressed ARs, 14.5 is the optimal length for me. I may change my mind later.Quote:

My 10.5 set up has an insertable gas port (the old pre-BRT tube solution) to choke the gas down to sane levels when un-suppressed. I've run both brake and flash hider style mounts, and I've never noticed a difference between the two.Quote:

If your brake has the same output as a standard A2, you will be allowed to use it. If not, please exchange or remove your brake prior to arriving at our facility, I have standard flash hiders to use at no cost to you. Contact me ahead of time.

Honestly, Clinton ban guns with Brakes are probably the only time a military style weapon has ever posed an actual health risk to the owner.Quote:

Same here. No brain damage from the blast. Just the glorious M4 bark.Quote:

I got to agree, even though I still have 10.3”/10.5”/11.5” uppers. The 14.5 P&W I can transport everywhere without issue.Quote:

Pin / Weld marries you to a muzzle device and if SBRing why not go shorter? - Not a lot of difference between the handling of a 16” or 14.5”.
I own one example and honestly would rather have the small increase in velocity of the 16” and flexibility of changing things around on the gun without dealing with the weld.
You have to get that muzzle device off to get the gas system off the barrel, which wouldn’t exactly be straight forward.
If I SBR something its going to be < 14.5".
Colt SOCOM barrels are a very good reason to go 14.5”.
That is a bit different and I agree.Quote:

My Colt "LE6930CK" upper half arrived today. It came in the typical Colt upper receiver assembly box. Here's a picture of the label along with a LE6921CK for comparison. Note that there's nothing on the box or inside the box that indicates LE6930CK. The label indicates that its model number is 63931. A search of the internet of that number along with Colt yields absolutely nothing other than a page showing that Botach is selling the same upper receiver assembly.

The bag inside was already open for some reason. Neither a manual or a muzzle cover was included as is typical with these upper receiver assemblies. As you'd expect, it's a 10.5" barreled upper receiver assembly with a BCG and a Magpul rear sight.

The railed handguard is the same one that was available on the 14.5" pinned and welded European 6920's.
https://i.postimg.cc/RFQXFfxn/6930-rail.jpg
The bolt face shows no sign of it having been fired. I don't know if that's typical or not for these upper receiver assemblies.

So, all in all, I pretty much got what I expected. There was nothing to validate Arms Unlimited's designation of it being a LE6930CK upper. In fact, the label seems to contradict that. These could be contract overruns, a one shot deal just because or whatever. I'm probably going to buy a Colt SBR lower half to put with this just for the heck of it.
Glad you are happy with your purchase. AU has had some interesting stuff lately. (At least to me)
Colt logo rail is pretty cool, too bad those don't seem to be available as an item for purchase.
FYI, Arms Unlimited is up to their shenanigans again. Prior to receiving my upper, someone had posted a two start out of five star review of this upper. There were valid points, but I think it was overly critical. Well, that review is now gone and there's a new review that's five star. While there's no good reason to ever manipulate such a rating system, Arms Unlimited really has no need to do so. Many of their offerings are unique and speak for themselves. I guess some people don't feel that they're not doing their job unless they're pulling one over on someone else.
On a more positive note, I was able to buy a factory Colt SBR lower half to mate to this upper.
Now it's getting a bit more interesting. Arms Unlimited is now offering what they call the LE6930. Aside from this same upper half, it has a Magpul B5 Bravo buttstock and the receivers are marked "M4 Carbine" instead of just "Carbine". Of course, the question is if this is an actual Colt factory built SBR or if it's something that Arms Unlimited put together from the uppers and lowers they have.
https://armsunlimited.com/colt-m4-cq...fle-10-barrel/
I sent an email to Arms Unlimited and received a good response:
"These guns started life as an SBR 6930-TPR01 from Colt. The TPR upper receivers have been removed and replaced with Colt 6930 upper receivers.
All parts and components are brand new. Barrel length remains 10.3" for both uppers, so there is no conflict on Form 4 submissions.
The box label will be marked 6930-TPR01.
I hope this explains everything. Please reach out to me if you have any other questions."
At least they finally came clean about creating new Colt models.Quote:

Side note, had my 6933-EPR to the range again last week and there is no way I'd trade that lightweight, free float Centurion rail setup for a quad rail version. I've got a 11.5" barrel in a lighter package.
