It is my understanding that these have 10.3" barrels, KAC RIS handguards, LMT fixed rear sights on an M4A1 lower.  Does anyone know if the receivers are marked or remarked as Mk18 Mod0?

I thought they were upper receiver replacement/upgrade, using M4/M16 lowers?

They are not marked MK18.

That's the way I understood them from Blackwater in December 2005.  They had the operators manuals there and it had them as replacement uppers for M4 carbines.

Correct:

LMT buttstock:

LMT rear sight:

www.fbodaily.com/archive/2005/04-April/30-Apr-2005/FBO-00797625.htm

The Carbine itself is acquired as a upper conversion and as a complete carbine.  As a complete carbine the lower is a standard M4A1, and as such would be marked M4A1 and have a W serial number prefix.  Colt is listed as the "sole source":


This procurement will be conducted on a sole source basis in accordance with the statutory authority 10 U.S.C. 2304(c)(1) as implemented by FAR 6.302-1. Naval Surface Warfare Center, Crane Division intends to enter into a Firm-Fixed-Price, supply type, Indefinite Delivery/Indefinite Quantity (IDIQ) contract with an ordering period of five (5) years after award, for the following items manufactured by Colt Defense LLC.

The MK18 is NSW's "CQBR".

LMT has been the sole provider of the 10.5" CQBR upper . Lowers are Colt M4A1's. SEALs deploy with a standard 14.5" Colt M4 and a "CQBR" upper w/ a KAC RIS/RAS. Most of them will have the LMT BUIS, LMT/Crane Stock, Aimpoint M2's or a ACOG w/ a J-Point and everything else that is offered in the SOPMOD package.

The Navy has recently issued the CQBR's as complete rifles to Navy EOD. I believe that is when you started to see the Colt shorty's along with the LMT's.

They don't come from Colt that way.

That is custom engraving job of some sort, the standard Colt MK18 CQBR upper, with the LMT buttstock and rear sight, as provided as per the links I posted earlier, and on a custom engraved late 60's or 70's lower receiver.

ETA, don't see a rear roll pin on the handguards, must be a RIS?

Note the T-markings on the side of the KAC rail?

Interesting.

I suppose you could letter them anywhere, but I do not recall having seen them at 3 or 6.

Here are some more pictures of older MK18's taken in the first half of 2003 during a State side SEAL training exercise.  The uppers are Colt MK18's that are circa 2002 or prior manufacturer (CAF forge code), lowers are modern Colt or at least FN, LMT rear sight and buttstock, and you can see these are RIS handguards, right side mag well is unmarked, unlike the other Navy picture just posted:

While not the Mk18, this would be a suitable replacement, and is likely attempting to do so.

Some of the "newer" ones don't have the LMT Buttstock and rear site. It's up to the individual SEAL if he wants to use the standard Colt stock or the LMT. Same with the BUIS. Both the KAC RAS and RIS are in use.

How can you tell if an upper is a Colt or a LMT from the tiny pictures? That platoon might have been issued some of the M4's that were cut down to "CQBR" length early on. Those photos are pretty old.

Navy Warships have VBSS Teams that do most of the "compliant" boardings now. That is one of their MK18's. I never said that it wasn't a MK18.

Bought this upper earlier this year on the EE, barrel dated 04/05.

Bought it from a Spec Ops guy on the southeast coast, said to be one of the Mk18 uppers, came with B/BC/CH and regular carbine handguards. I provided the rest

copy of his email
--------------------------------------

Blake,
  Here are the pics of the MK18 upper. Along with the
Eotech or Aimpoint, LMT Fixed BUIS or KAC BUIS, a
single point sling, PEQ-2A, add the KAC RAS and
forward grip. Best Regards,
                                   Danny
---------------------------------------------------------

The pictures were internet training pics that showed what the upper looked like,

Danny is on an entry team, and is also an instructor, he says alot of the times he will do instructing for parts, "a good way to support the Colt habit"

I ended up buying 3 different uppers from him, he has the wherewithall to come up with some awsome stuff, I got real lucky in my connection with him, right place at the right time, that does'nt happen too often for me,

Maybe he'll see this thread and chime in with what he knows

When you expand the picture, you can see the Colt forging codes.



Most of my other MK18 pics are older, with the Crane rather then LMT stocks, and KAC rather then LMT rear sights.

Those pictures are all freaking huge, your computer is shrinking them down to fit the screen.

a 10.5"-er !

I love that look.

I had read that (Colt) barrels less than 11.5" were finicky shooters. Those who use these on a professional basis cannot afford to have them choke at a bad time.

But I suppose the right armorer can tweak the gas port in a way that they behave properly.

Found these in a discussion at another Forum.

A lot of different Carbines floating around!

Also, makes me wonder how many of the Carbines in the field are in USGI form, and how many are modified at the unit or field level.

In my research on the Pre-M4 Carbines, I have found plenty that were modified at the unit or field level.

Thanks to everyone for sharing the info. Congrats to Grant.
