Colt Canada Modular Railed Rifle

I like my CC IUR rifles. But I don't mind a bit heavier for the durability. With Police patrol (assault -couldn't resist-) carbines it's better to have something built like a tank as it will take abuse. With firearms not individually issued they really have to be tough.

The barrel and gas block access being a problem isn't specifically a monolithic upper problem. The LMT mrp for instance is also monolithic and you can easily change the barrel yourself. Truth be told I actually prefer my LMT mrp rifles over my Colt C8IUR rifles. LMT also released a slick slided version a few years ago. Not sure if it's mlok or keymod.

Being Canadian it's pretty hard not to drink the Colt Canada kool aid! They are fairly nice duty rifles. I wouldn't pick one necessarily for three gun or competition. But for patrol or combat they are pretty tough. Plus it's more affordable kook aid than HK!

True. But i was referring to stuff like offset mounts.

And just out of sheer curiousity i would like to try to see if mlok pieces can be fitted to the 45 degree positions. Im guessing no. But worth a try.

So much agree, I can't agree more.

Good Canadian guns seem to be like Canadian hockey players; not superlatively fast nor entirely cutting edge, but tough as #### and more than capable of getting the job done.
 
I like this one. They say it's around three quarters of a pound lighter than the original IUR and all that weight was shaved from the front of the rifle. This one will be much faster handling rifle, with much better ballance.

Love it.

Calgary Shooting Centre does it, 150$ a hour and about 3 hrs with adding taper pins to the new barrel. Which you'd have to supply or buy from them.

Yeah but I have to supply my own barrel. I want a genuine Diemaco 14.5" barrel.

You don't need a monolithic upper to stay free floated. Kac, hk, bcm makes awesome rails that are not monolithic. So you're telling me that I can't shoot supported with my mr223 without having a poi shift? That's interesting.

It is a fact that bolt/clamp on free float tubes will reduce POI shift.
That said any free float tube that hangs off the barrel nut will suffer more POI shift (than a properly designed monolithic upper) as they load the receiver at a rather thin point and steer the barrel by deflecting the barrel nut. There is after market free float and there is designed to be free floated.

Rail shift.
With the increased use of rail mounted lasers and NV (in the professional realm) the ability for the rail to hold zero becomes more and more critical, and the simple fact is that a one piece non removable rail is going to hold zero better than anything that bolts together/ comes apart regularly for cleaning.
 
We did some intensive testing at sig sauer academy during an advanced rifle class 2 years ago. Unless you put exessive weight on your handguard, you will experience slight a shift of POI but its' minimal. Even at 300m which consider to be the max effective range of the AR15. We tested different rifles and to be honest, that's not something to be worried about.

When shooting from a barricade, you aren't putting much weight on your rifle anyways. Monolithic uppers are a thing of the past. But at least, they adopted MLOK so there's still hope.

And yet, here they are.

Luckily we has consumers have lots of options. If monolithic uppers don't work for a purchaser, there are plenty of quality ARs to chose from. Might not be CC but quality none the less.

Face it, CC is not going to change their manufacturing plans because a few random unidentified folks on an internet forum tell them too. If their customer base demands something else, they will build something else. By customer base I mean large scale LEO & Mil customers.

That being said, I've given up totally trying to guess what CC will come out with next and why. For all I know it could be a dedicated 22 upper and bolt, or 7.62x39 or.......
 
Lol, Antoine22.......

you are quite a bit underestimating at 300 meters... by 50%

m4 max effective range of a point target 500 meters
m4 max effective range of an area target 600 meters

an 18 inch barrel will stretch that area target range 20%
20 inch barrel will stretch that area target 30%

No offence, but what durability? A pencil barrel is just as strong as the fat pointless profile of a gov barrel without the nose heavy balance and extra weight. They're firearms, not battle axes, shoot the person don't beat them with it. What I see are excuses from people to justify being sold a ten year old design and old inventory at inflated prices.

The current IUR that's available is a very dated design and a fat pig, not to mention it's carbine gas. Monolithic is not the greatest idea and the LMT MRP was a flop. Changing barrels(MRP system) means re zeroing optics, dumb system. There is no need for "rapid" barrel change capability. Swapping tops is easier and faster. Damaged hand guard with a monolithic means changing tops, dumb.

If a guy has no desire to change hand guards than the new IUR/MMR is a slick looking setup. Avoid the issues above and you're golden!

Are you using fragmentation and yaw upset distances for M855 ammo as your baseline? Not that it's incorrect, but I still wouldn't want to get shot outside of those ranges.

Not really. Muzzle brake, compensator, plastic mags, angled foregrip, mlok handguard etc... you really think that this market is driven by Leo and military customers? You really think that shot show is dedicated to Leo and military customers ?
