Canadian modular assault rifle project, a C7 replacement?

[IRepoCans]

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.

If the guy's doing the barrels are Canadian, we're not going to see the insane performance gains that hot loaded 5.56 is capable of, full stop (the black magic of barrels at this juncture, oddly enough, is French).

I'm also quite aware of the ballistic change, the current C7 also has a 20" barrel to be more accurate for your calculated loss of velocity with the in-service C77 ball to a 12.5". I'm also saying that the average shooter should be able to touch 400m quite comfortably with the current C8CQBR (let alone a C7 or C8) that has an 11.5/11.6" barrel. The problem at the moment is the shooter, but others and myself have beat that horse to death enough as it is.

The GS platform's barrel length is also a 11.5, be cool if it was a 12.5 but it isn't (I'm honestly a huge fan of AR15s in the 12-13" space given what's possible with barrels and suppressors now). The big question in my mind is if the GS and FS variations will share the same muzzle device (and mounting collar), because I know what I'd rather have in a deliberate OP or hide site if I have a can mounted.

The signed SOR is also accessible enough on acims for anyone who wants to look at what's specified.

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.

At worst it's an inconvenience, a lot of excuses are made on length before looking at training (or lack thereof). The workhorse of USSOCOM is still a standard length M4A1 with a suppressor for something with a similar overall length of a C7, and that goes for a lot of the AR15s in Ukraine as well.

Not discounting that a shorter profile makes all of that nicer, but I've found that a lot of the time it's more of a skill issue than something inherently wrong with the length of the weapon system. Biggest boon will be for the mounted lads embarking and disembarking.

Can you speak to the optic powers for both variants?

The optics package is in a weird spot, I know they're hard set on a LPVO for the FS which I think got finalized (pretty sure it's the SAI 1-10 power for the FS)? But the CCO with magnifier is all up in the air, and the clip-on sight(s) are also contentious as it might just get pushed off onto NVSM to deal with it.

EDIT: And because there's actually nothing really out on this, anyone know what the solution is going to be with the M203s? Figure they'll just drop them into a standalone kit and call it a day.

GS was looking in the 4-6x, upto 10x zoom was being sought for the FS. I havent seen specs on the final optics chosen

I am reading all the above from you experts and I am starting to think that my old FNC1 with 7.62 cal bullets sounds pretty good ... even if it was heavier.

Well, there's a 7.62 sharpshooter rifle now in the section, doctrinally at least, pretty sure it's just going to be the C20 with a different optic package from the SASR.

In what doctrine? Like which pub, we briefly had that in Afghanistan but it neither exists in concrete form or in the infantry platoon in battle, that I've read that is.

In Section and Platoon in Operations Chapter 2 (dated 21 November 2021) says there is one sharpshooter per section. It does not specify what the rifle is or what calibre it is. It does say that they have 100 rounds in 5 magazines and another 100 in bandoliers, additional magazines or loose rounds.
