Colt Canada IUR 15.7 PREMIUM CARBINE

[fenceline]

Pardon my ignorance, why is full auto bicg required in semi guns? Does it make a difference? Can you double tab faster or something like that?

Some people want it because they feel it is better. There are several different styles of bolt carrier. Sometimes the extra mass helps.

Honestly it would be nice if Matt chimed in to give his thoughts.

[r34skyline]

Given everything else they produce, at the quality, care and control that they make those things, I highly doubt colt Canada would risk their reputation on changing things in that process to make a sub standard bolt carrier. In fact I would go so far as to surmise they were made on the same assembly line, with one step added to mill away that extra little section on the underside so they wouldn't allow a full auto lower to function properly.


If I were to play the odds...

You are probably 100% correct there. But keyword there was play the odds. If you think it's good enough(and i don't blame you if you do) power to you. I prefer the known over the unknown. The design while in all likelyhood solid. It's not proven so. If matt k wants to chime in to prove me wrong he is free to do so.

I'm sure I probably missed something.

Interesting.
I have an SA20 and 15.7. Although they are separated by 800 or so numbers the rails look the same.
What serial did they start using weaver rails?

No idea. As the uppers aren't serialized and they install one on any number of lowers set aside for the project it could have no rhyme or reason to the lower numbers.

That being said, the weaver uppers didn't come out until near the end of production of the sa guns. Most were on sa20 versions but some were on sa15.7.

The number of rail sections are different and the tang above the charging handle is stepped down near then end of the rail.

The IUR has the same step on the tail end of the rail.

 

[Repro77]

It does. But IURs are the only upper CC produces now. No more front sight gas block uppers. So that is a discontinued model and design. If that's what someone wants, that is the only way to find one. For those that like to modify those guns, they are easier to change a rail on than and IUR, that's for sure.

Apples to oranges within Colt Canada stuff, sort of.

Maybe so, but if someone just in the game is looking for a complete, genuine, factory assembled CC rifle, and not particularly invested in either particular upper's setup, which one would they choose?

Colt Canada's current game of releasing things in drips and drabs, undercutting previous offerings pricing with "blemished" product later on, does them no favors. We also have to deal with the "limited" aspect of these offerings as well, with more surely to show up later on as "overruns", "blemished", or whatever other marketing terms they can think up to sell/hype their product.

But I'm sure they will sell every one. Hey, I bought an original IUR, so they got me too!

I just went and measured mine. Both are .206 of an inch which makes them picannity.
The SA20 is in the 800's and the SA17 is under 100 as far as serial numbers go.

Extra mass to the bolt does nothing for recoil.
It will increase dwell time, but recoil is the same.

You don't need to measure. Just look at the rail and see if it has a step milled out of it above the charging handle. The our has the same step. Weaver has a step, pic doesn't.

None of these used a weaver. Even my son's early SA20 measures .206 of an inch in the rail. Weaver spec is around .180.
With or without the step it is still a picatinny spec rail.

I stand corrected.

Still, two different types of upper. 13 slot and 14 slot.

I can tell you exactly what Matt has said about SA bcgs: if a gun doesn't have full auto, it doesn't matter what bcg it has.

And the SA bcgs are gtg; need not worry.

Seems very accurate to me, well done.

In fact I would go so far as to surmise they were made on the same assembly line, with one step added to mill away that extra little section on the underside so they wouldn't allow a full auto lower to function properly.

If I were to play the odds...

I have no clue if these will perform on par with either a us mil spec m16/m4 bcg or a can mil spec c7/c8 bcg. Cc has not given any demonstration on how these hold up to hard use compared to a mil spec bcg. I traded what I don't know for what I do know. Till someone demonstrates the sa hybrid bcg can match or exceed fa bcg for reliability and longetivity i see no reason to risk with the unknown when i can run the known.

That's the CC advantage, that being their are no odds to play when running CC kit since they only produce very well prove and extremely reliable rifles and rifle components.
CC leaves no doubts (for me at least) as I trust no rifle leaves their facility w/o being exhaustively tested in design/use allowing the rifle or in this case a BCG to pass their extremely high standards which you can be sure are significantly greater then what 99.99% of CGN shooters will ever put these restricted rifles through.

It seems odd to me r34skyline that you would spend such a high price for a product you seem to have such little faith in?

With regards to the long compilation lost made by fence line, my understanding is that the latest offering by SFRC has a CC BCG, not a generic one.

I think Fenceline means the latest models with CC BCG's in this highlighted line, at least that's how I understand it as the F/A BCG's are from CC.

Now the big question is how long until we can buy the Colt Canada MRR?

Now that's pretty cool, but looks too similar to the custom build I'm working on. So I'm glad that I got the version I did.

Still if that is released I think that's pretty much the ultimate one stop shop rifle money can buy.

1) i didnt buy the sa20 i won it in a raffle.

I did buy the iur right at release because it fit my dmr build perfectly.

2) i never said the hybrid bcg are lesser than a milspec unit like dd bcm or lmt. I said i don't want to risk running the unknown. I don't know if the hybrid bcg will be as reliable in adverse conditions or long lasting as a mil spec piece

It's the same story with the mr556. Odds are it will be very reliable and durable but i don't know if it will perform on par with 416 or its mil spec rivals.

Like fenceline said. It's rolling with the odds. I choose to put my trust in what I know. I dont know if it will perform on par. I'll go with the known standard instead.

Actually I wrote there are in fact no odds to play when running CC kit (it was Fenceline that mentioned "if I were to play the odds"... if only in jest I think) and I would say the same for HK as well (with regard to the MR223 you speak of or any of HK's products just like CC, both these companies are at the pinnacle of military small arms design...).

Because I believe these companies produce superior quality firearms/systems parts and like anything they produce, nothing leaves the factory w/o being thoroughly tested and proven.
By that I mean nothing is offered w/o being throughly tested to a standard that goes well beyond what 99.99% of CGN shooters will put a restricted rifle through in Canada.

Also (IMO) it's fair to say that CC doesn't offer anything that isn't better then mil-spec. (as CC has made over 100 hundred improvements over USA mil-spec which many would consider the basic standard to judge from) and (IMO) believe their semi. BCG's are to that same standard and quality as the F/A BCG's.

I say this knowing that our LEO's are putting their lives on the line running these very same semi. BCG's that come on the CC SA rifles in their issued CC rifles; so I highly doubt CC would cut corners in either their development or design/testing (and HK likely is the same with any of their civilian/LEO products).



BTW congrats on the SA20 prize, must have been an exciting moment and with your IUR purchase you know have a very sweet set-up.
