That monolithic upper reminds me of my Aero Precision monolithic upper, just a bit more refined.

http://aeroprecisionusa.com/ap/c-o-p-monolithic-upper-receiver/  -- scroll down to the different side-rail choices, and they basically look the same.

Nope.
That is definitely a real SAS operative, but you did have good reason to assume such.

No airsoft companies have made the monolitic IUR, but Angry Gun has made L119A2 IUR handguards that can go on your WE gas blow back rifles. However, it is a hanguard you screw on a barrel nut and is not monolithic, and looking closely, you can see a gap between the upper and handguard. I believe the make long carbine and short SBR handguard configurations.

Yes, 100% sure.

It is VERY common for UKSF to wear airsoft masks for PERSEC reasons.

Not a L119A2, but it is an IUR. Check out what Larry Vickers recently posted.

Early Dutch contract variant, 15.7 barrel.

Definitely. I just now noticed that in front of the hand guard, there is a screw below the rails on the 3, 6, and 9 o'clock positions to add on a hand guard extension like their current service rifles. I was under the impression that the Dutch IUR was a Gen.1 while the Danish IUR (with and without QD slots) was a Gen.2 and the L119A2 was a Gen.3 IUR. Am I wrong? If so, please correct me.

The official word from Colt Canada is that there is no Generation designators on IUR, simply specific variants for country requirements.

Here's a clear photo of the receiver extension, extension nut and receiver.

You'll notice that the threads are machined away, unlike on the American counterpart, and the extension nut is often referred to as the older Colt style. The reasoning behind the deletion of the threads, and the older style of staked nut was due to the NBC gear requirement of the CF. They determined that the threads and the newer version of the nut - the actual castle nut, had a high risk of cutting the gloves of the CF's NBC gear, should they theoretically ever need to use it.

Clearly, that has carried forward into what Colt Canada continues to manufacture. The image also shows Colt Canada's newer style of receiver endplate/sling attachment point.

pm or comment if you guys want any more detailed photos of the lower receiver.. or the upper for that matter!

Cheers

It should be noted however, due to thread title, that is NOT the endplate issued on the L119A2.

The Magpul ASAP is issue for the L119A2.

Can you start an additional Canada specific thread? I'd love to get more info on the Canadian rifles, which are different again to the UKSF models and it seems like you have enough info to start such a thread!

Absolutely! Happy to start a Canadian thread - you are indeed correct that the Magpul ASAP is the issued sling for the UKSF - whether they were installed by Colt Canada, or by the UKs armorers I can't comment.

thank you for the images of the gas block, these are the first images of it I've been able to find!

True North Arms will start selling IUR wrenches (as well as barrel nuts) soon. Link

Apparently Colt Canada IUR wrenches are available through Nordic Marksman (but not listed on their site), but I haven't heard back from them yet.

Would a 6940 wrench work with a Danish overrun IUR?

Does the MRR use the same barrel wrench as the IUR?

Interesting, because retailers advertise the Danish and British IURs as "Gen3"

I've always wondered what the "Gen2" IUR is...perhaps the RCMP's IURs?

O'Dell are responsible for the incorrect information floating out there such as 10.5" and Gen3.

To anyone that has dealt with O'Dell, that will not be a surprise.

True North Arms are good people. The price on their wrench is very fair.

Unlikely nordic will sell you anything other than the OEM colt one which is $$$$$$

Go on...

Disappointing (and surprising, don't they have a close relationship with CC?)

Excellent! (What have you purchased from them?)

I think it was in this thread (or the L119A1 thread), but $800 was mentioned.

I'm looking at rebarreling one of my uppers, possibly with an 11.5" (due to price and scarcity, probably not a CC barrel) or 12.5"

Phil (?) O'Dell used to work for CC I believe.

O'Dell are the only distributor for CC parts, resellers must buy from O'Dell but the joke is that ODell customer service is about as bad as Comcast.

Here is their pdf of lies

Nordic Marksman has stripped 10.5" IURs for $1,299.95 (No BCG or charging handle), or the complete rifle for $2,299.95.

Well thats the point, it doesnt.

It has 10" uppers. No such thing as a 10.5"

There's a thread on CGN where Nordic posts a pic confirming/proving it's actually 10"

Is that what you mean by "pdf of lies"?

elucidate's L119A1 and L119A2 threads have been are a treasure trove of info.

I've been taking notes.

Y'all cloners are a different breed.

What is the length of the IUR rail/handguard?

I just realized that. Thanks for clarifying that for me. I never knew that O'Dell Engineering was a distributor of all Colt Canada items, and that they would get their facts all wrong. I can understand European military requirements and what operating roles where a 10" barrel rifles are useful in, what I also don't get as to why Colt Canada doesn't have a 11.5" offering to resolve the dwell time issue?

EDIT: Scratch that, never mind... Some C8-CQB models do use the 11.6" barrel for Allen Engineering/Ops Inc sleeves to mount suppressors and Colt Canada also has a 11.6" MRR variation (or is the barrel length spec wrong on this one too?). Man, I would kill to own one of these... I'll take that over a BCM SBR rifle for my main SBR fighting rifle any day!

Barrel length is correct - it's 11.6" (go figure).

I have read somewhere that 11.6 and 15.7 lengths fall on an "accuracy node" for the barrel profiles/ materials Colt Canada uses. Something with barrel harmonics. Or some Northern witchcraft maybe

Or that's just a leftover from the imperial->metric->imperial conversion.

Makes as much sense as arbitrarily using 14.5" because we needed to fix bayonets on the M4.

Just wanted to let you know I really enjoy these threads. Seeing the different technology that is being used across the pond is really interesting, thanks for taking the time to post about it here!

If there was a reason behind it, then it can't be called arbitrary

Obligatory link to Larry Vickers' post on the Cansof IURs.  Interesting set up they have with the AEM cans. Seems a tad different than what the Brits SOF is rocking.

The CanSOF C8IUR compared to the SAS L119A2 seems to be the exact same except for the lower roll mark and suppressor mounting muzzle device. Interesting...

CanSOF C8IUR is missing the grenade launcher lug underneath, and also has the 11.6 barrel with collar for the Ops Inc can.

Great thread, thank you.

I want to build a clone of that rifle.

I forgot to point out the barrel length, but basically a longer barrel to accommodate the Ops Inc. collar/suppressor. 11.6" is superior to the 10" for the dwell time, so I find it interesting that the Brits still use the 10" barrel.

I totally missed the excluded grenade launcher lug. Good eye and thanks!

I wish I can have the real thing! You got access to the upper up north. All us American Colt Canada enthusiasts can only sit by and watch...

The barrel nut is the same for the IUR and MRR.  I have had the barrels stripped out of both at one point.  Trying to mix and match.  I would like to see the RCMP IUR's made available to us civi's.

Bump

I don't want to have this awesome forum archived just yet. I got something special coming that is very relevant to this particular forum. I'll give details and photos soon!

Contact a mod in this sub-forum and ask to have it turned to "do not archive".

I am planning on doing a clone for the L119A2 just because I thought it would be a fun challenge. Plus, I have quite a few Colt Canada parts laying around, so I decided to gather some more parts to help complete the build. It is pretty difficult to import a IUR upper from Canada due to ITAR, so I want to avoid any fiasco as possible. Not to mention that I heard that Colt Canada will stop selling the overrun L119A2 uppers to the Canadian civilian market in the future, just like the Danish IUR overruns. Who knows, maybe I stumble on a set? But for now, if you have followed the Reptile House blog, there might be an alternative.

I'll update with more information and photos in the future.

Here is a HAO industries L119A2 upper. It comes with a lot of accessories, but I'll just go over some key details. This upper is mostly the same dimensions as a real IUR upper being CNC from a single billet of 7075-T6 aluminum, but it will need some modifications before it can be used for live fire. I warn you, this upper, along with sourcing rare parts is not cheap.



The "COLT CANADA 2C085" is not dimensionally 100% correct, but is raised, so that is a huge plus. Also note the correct LMT patent number (I used rubbing alcohol to take off the black paint over the number). The other side has the correct Brass Aluminum square forge code and stamped "NATO" markings. Also note, the grenade launcher lug is machined into the upper and is not a separate piece held in by a screw (the screw will be installed after this build is complete).




HAO Industries have staked the steel latch, but only one or two strikes with a round nose punch, thus the latch being loose in place. I went ahead and took a flat steel 5/32 punch and took it to the grinder to make a square for staking castle nuts and staked the steel latch in place. Also I have painted over the bare metal with a Birchwood Casey AR15 black pen. Unfortunately it is not super pretty, but it works and is "square" enough for me. Now the latch doesn't move, and I probably would have been able to stake it better if it wasn't staked before.



The ambi charging handle it came with is thinner than a mil-spec charging handle to make room for the PTW cylinder, with a longer rod in place for the HAO recoil/charging system. Oddly, the HAO charging handle is longer than a mil-spec, this it does not fit properly (I'll get a photo later). A real Colt Canada charging handle fits perfectly on the HAO IUR like any mil-spec upper.



Here you can see the serial number which shows the 11th one made. Note the lack of a cam track. To get this upper operational, a cam track will need to be milled as well as a hole drilled for the forward assist. Also two detent holes for the dust cover detent.





I also picked up a Colt complete BCG from Thoroughbred Armament, but these lack the "C" stamp on the carrier. I don't like how Colt is placing cage codes and not having C stamps on most of their equipment for easier access to parts for clone builds in the future, but this works well for me as it allows me to engrave a "CC" on the carrier.



Here is the carrier in the upper. I will note that it is slightly loose, but still should function.



Some of the accessories it came with are a gas block and heat shield. The gas block will need a hole to be drilled for the gas. I also have here a Colt LE6940 straight gas tube. The gas block will need to be slightly reamed for the gas tube to fit (unless the second one I have on order will fit).



Rear take-down pin is a tad tight, but the upper seamlessly meshes with my BCM lower.

The only parts I need to finish other than the machine work, are:
- Barrel
- Aimpoint T-2 with GG&G mount
- ATPIAL-C PEQ-15
- Surefire FH556-216a flash hider

Even better, a Surefire CA556SA flash hider for my L119A1 so I can use my FH556-216a I have for the L1192 project. As for the PEQ, The SAS use PEQ LA/5 with black and white sticker labels, and I have an airsoft PEQ LA/5 as a stand-in. Real PEQ LA/5s typically cost a few thousand dollars, and more as a brand new PEQ for government contract order. And I don't have the cash for a new PEQ-15c either.

I have to admit, Colt Canada looks great with BCM and Scalarworks gear...

Huh, interesting. One of my complete "M4 Carbine" lowers from Brownells came with a buffer just like this. The other 2 had standard "H" marked buffers.

That's a bold plan, using the HAO upper...
