Canadian AR question (AT vs CC vs DLASK)

Well...

The Diemaco SA20 is in fact a semi-automatic version of the C7 so named because the RCMP require a unique model name for the rifle to be issued an FRT and classified as restricted. There have been several semi-auto only versions of the C7 in the past, and the rest is just playing at semantics.

Colt Canada is a wholly owned subsidiary of Colt's Manufacturing in the USA. The rifles are not Colt rifles. Colt produces up to 650 rifles a day, Colt Canada is capable of producing that many in a month. They are made from a separate Canadian technical drawing package. The Diemaco rifles are made in Canada by Canadians. The materials are sourced separately and the production processes are unique to the Colt Canada. The Diemaco rifles use all of the same materials and processes as the military versions, The difference is essentially less material was removed from the inside of the lower receiver to make it semi-auto only. The quality programs, coatings, etc are all the same. The semi-auto components are identical to the semi-auto only C7 and C8 components used by LE customers.

The fact that Colt Canada is owned by Colt's does not make these American rifles or change the fact that they are made by Canadians in Canada by a company that directly employs 100 Canadians and supports over 80 Canadian sub-contractors and contributes to the Canadian economy and Canada's strategic defence capabilities. The fact that Colt Canada is owned by Colt now is the main reason Colt Canada was able to offer a version to the commercial market.

Spec is NOT Spec. There are a number of pretenders that misuse the word "MILSPEC". There are hundreds of standards and specifications. There are differences in Canadian and US specifications. For a rifle to be MILSPEC it must be produced from the official government TDP, using specified materials and processes in an approved facility with Government approvals and inspectors. The rifle must have passed the official acceptance checks and the design must have been certified as safe and compliant to the entire NATO and government test packages. It must demonstrate the ability to fire all NATO ammunition. The rate of fire burst test is one of only hundreds of required tests and can be waived for semi-auto only rifles provided they meet all the other requirements.

Most of the design changes from the M16A2 that won the SARP trials were dimensional. We will not be providing a list of those dimensions for what should be clear reasons. Nearly every dimension in the Canadian rifles falls WITHIN the US tolerances. There were changes to make the rifle markings bilingual, changes to heat treating and materials as well as changes to acceptance checks. In every case the change resulted from a stricter requirement.

The Canadian specifications call for a unique hammer forge process that was developed here in Canada specifically for the C7. The advantages include a huge improvement in wear resistance, strength, extreme cold weather performance, accuracy and barrel to barrel consistency. The advantages go far beyond the choked barrel that allows for accuracy to last much, much longer through the life of the barrel. The barrel blank material for a Colt Canada barrel costs more than a completed M4 barrel - for a reason. The process creates thousands of identical barrels with perfectly concentric chambers. This contributes to accuracy so much that the accuracy spec for barrels at Colt Canada is exactly half of the US MIL-SPEC. Every barrel is air gauged, bore-scoped and fired for accuracy - commercial or military production.

Further, the chrome is improved over the US MIL SPEC to handle much colder environmental testing. The Colt Canada improved carbine chamber makes the carbines the most reliable in the world and the number of tier 1 units using these is evidence enough.

The Weaver rail on the C7 was dropped for the commercial SA 20 and SA15.7 versions so that commercial optics could be used. There are a number of countries that use Canadian select fire C7/C8 with MIL-STD-1913 rails as well. In fact, the Weaver rail pre-dates the MIL-STD-1913 standard rail and had several advantages including better repeatability and better accuracy. This is why the new NATO rail standard uses several of the features of the Weaver rails, and why the MIL-STD-1913 is being replaced.

The furniture is all C7 and C8 furniture selected because it meets all applicable military specifications such as surviving drop testing, temperature extremes, chemical resistance etc.

These rifles are the only MIL-SPEC rifles you can get that are made in Canada. There is no other facility that has the official Canadian and US TDP, the government inspection program or mandated quality and material programs. There is no "seconds" line of production. It is not allowed by law or by the mandated quality programs. There is no way to separate out lower quality parts, so none are allowed in. These rifles are made by the same people to the same standards with the same materials and processes with the same care as all the military and LE rifles produced here for the last 30 years. They are not only the same pedigree as the military C7 they combine all of the experience and updates Colt Canada has included in that time period as well as the extensive expertise of our American cousins.

I can verify that these are made to the same specs as military rifles. I would not hesitate to go back to Afghanistan with an SA15.7 or an SA20.

First off, thank you very much for the great repsonse, it clears up some questions for sure.

So at the end of the day the rifle is a MILSPEC(as in US MILSPEC) AR with a reportedly improved barrel and a improved chamber. Can you indicate what has been changed/improved on the chamber to make it so reliable?

TDC
 
I well aware of the benefits of CHF barrels, its what I own and prefer. However, its primary benefit is longevity, not "accuracy". A CHF barrel that meets MILSPEC is the same as a broached barrel that meets MILSPEC. To spec is to spec.

I'm still waiting for the list of differences between a "C7" and a standard MILSPEC AR like the M16A3? Both are 20" barreled select fire rifles of the AR family of weapons, no??? No one seems to know just what these "specs" are that the CC rifles are being measured against. It was mentioned in another thread that there are "about 150 changes" but not one has been listed. Some unfounded crap about a modified bore that "Squeezes" the bullet?!? WTF is that? I'm quite confident that two rifles side by side, one being a CC one being a copy from a reputable brand made to spec(DD, COLT, BCM, LMT) would print similar groups and be indistinguishable as far as performance goes. The only visible difference is the skinny front sight post, a $24 fix(brownells) for a 7 pack of various slimline front posts. None of which are useful during lowlight....Just saying. Can anyone list these differences that a CC rifle has that another AR does not??

My issue with the "C7/C8" label is that no one who owns a CC rifle owns a C7 or C8. They own a SIMILAR(not exact) copy of the two aforementioned contract "spec'd" rifles; or so we are told as no one seems to know the specs nor can they prove the CC rifles are of the same pedigree. The wannabe fanboy sh*t about "look at my C7" is pathetic. YOU DON'T OWN A C7! You own an AR built by COLT USA, in Canada.

My statement still stands. Of the brands listed by the OP, the CC is the better choice. I don't doubt they make a decent rifle, I do doubt that its a super duper uber high end masterpiece that commands ones worship..

TDC

How does increased longevity not equate to better performance? Accuracy isn't the only thing that measures a barrel's performance.
And for your information, being select fire isn't necessarily a characteristic of every C7/C8. The C8's the cops get for instance, are typically semi auto only and are still C8's. In addition, the only one here saying people are calling their SA20's or 15.7's as C7/C8's, is YOU. Any time I've ever referred to a C7 or C8 is when talking about the one's I was actually issued in the CF, which is what you're making your hissy fit out of, because you think it's just a Canadian mil term that shouldn't be used, that it's a "stupid designator". I haven't seen anyone on here claiming to have a C7 or C8 when talking about their personal rifles, though technically, much to your horror I know, they wouldn't be incorrect if they did.
And telling me that I just own a Colt USA rifle, laughable. Really that's unbelievably ignorant..

thanks for the great reply!

i have a question for ya.
i live in the far north and i have infact had several AR's freeze up on me over the years.
i see mentioned a few times in your reply you state that CC has engineered the C7 for extreme temperatures.
can you tell me a little something about the C7 in extreme cold?
because this is a point that i have great interest in.

im gonna be stopping by one of the listed companies that sell for Korth to see about the availability of getting one of these.
 
So at the end of the day the rifle is a MILSPEC(as in US MILSPEC) AR with a reportedly improved barrel and a improved chamber. Can you indicate what has been changed/improved on the chamber to make it so reliable?

TDC

Couldn't you understand from the post made by Colt Canada that their C7/C8 or SA20/SA15.7 as you would have them be called are in fact not US MIL-SPEC, but are in fact better by being an improved version known as Canadian MIL-SPEC that not only meets, but surpass' the US MIL-SPEC standards in many areas. COLT CANADA also points to the fact they cannot give away certain details of their build procedures/materials due to maintaining a competitive advantage over their competition. Which is a reasonable practice for any leading company to maintain, not all trade secrets are available to the public.

Really why do you have such an issue with Colt Canada making one of the best AR rifles for military service in the world (as proven by actual endurance tests and by the leading top tier SF teams picking COLT CANADA to supply their rifles).

The secret to keeping an AR running when it is stupid cold out is decent lube and keeping the rifle dry.
