Canadian modular assault rifle project, a C7 replacement?

[PrairieFella]

Possibly the CMAR announcement?

Secretary of State Fuhr and Minister McGuinty to announce new investment to deliver modernized capabilities to the Canadian Armed Forces - Canada.ca

The Honourable Stephen Fuhr, Secretary of State (Defence Procurement), and the Honourable David McGuinty, Minister of National Defence, will announce a new contract that will deliver new capabilities to members of the Canadian Armed Forces.

They are located in Kitchener.

Do the numbers for the Full Spectrum version seem low? I'm wondering if there'll be enough for the reserve infantry units to get that version?

Full spectrum is only for the infantry. It includes a longer barrel compared to the GS, different optics and a surpressor, with an optional TWS.

Note the announcement also covers new ammunition. Which is a new ball round, which will give the GS an effective range of 300m (with a barrel even shorter then a C8) and the FS will have a 400m effective range for individual fire.

Must be a spicy round. Whays different about it?

Id tell ya if GD would tell us, unfortunately things are tight lipped about the new round

 

[MrWhyt]

this is still some evolution of the 5.56/AR-15 yes?

I was wondering the same thing. Is this still a DI action, or has Colt moved to a piston driven action like HK?

I guess we'll find out this year lol

I asked someone close to the project whos been in industry, answer i got was a lecture as to why piston driven isnt the correct term and even industry people mis use it. It sounds like it might be DI but I am not 100%

Hotter charge but otherwise it is a 62gr with a steel core and penetrator; but unless CC is changing up who they're getting their barrels from, their go-to barrels aren't really going to get much out of it and with slightly less barrel life.

The current C7/C8 is already effective to 400m as an individual at the deliberate rate, and an 11.5 has always been able to comfortably do 400m from my experience.

It's a DI gun, only change to the gas system is a straight gas tube which is inline with the IUR/MRR package (and maybe an adjustable gas block). It's unfortunate we're not learning from the CANSOF troubles with the IUR and going with upper with a COTS barrel nut mounted free floating rail that is lighter and that can actually dissipate heat without becoming unreasonably hot during a break contact drill.

Point 1. I cant go into details but the barrels are different

Point 2. I dont think you understand how dramatically the ballistics change with barrel size reduction. If you take the current C7 with a 18.5" barrel and drop that to 12.5". Youll lose 250-350 ft per second in velocity, upto a 25% reduction in kenetic energy, and massively noticeable difference in performance past 300m for the average shooter. CMAR and its new ammo aim to keep those ballistic properties of your 18.5" barrel and meet or exceed them in a 12.5 barrel. Pushing further with the FS.

I am starting to wonder what kind of chamber pressure they are planning on pushing in the CMAR…

Let's just say for now that, thats not only accounted for but we will see an increase in life span of the rifle

The real question is what ballistic energy is required, at what range, and what handling trade off is worth it. There isnt much benefit to have a 400m capable rifle if were expecting infantry soldiers to be clearing trench systems, forests, and houses where that 18 inch barrel is at best a liability. CMAR is a good step forward.

You also have to factor in a surpressor being added to compensate for the increased muzzle flash of a shorter barrel. Its a very well thought design

I will take your word for it, but, we just had an example in the US Army where someone thought that pushing 100k psi was a good idea…

Thank fuck we ignored that 6.8 noise. What a logistical nightmare that would be.
