Canadian modular assault rifle project, a C7 replacement?

[MilEME09]

What ammo spec are we talking here? I've seen video of 75 grain bullets travelling at 3500fps, with a pressure of 100000 psi! I would agree with @KevinB that is a substantial increase over standard NATO 556, which is generically described at 62 gr/~62000 psi. That will be punishing to barrels no matter the metallurgy...

GD has been tight lipped I've heard rumors its 72gr but nothing firm. Asked my contact and he said GD has been stone walling them.

Slightly different topic, confirmed the surpressor on both version. It is also fixed....so I have one question, where's the BFA go?

I have heard rumours of a “Holywood blank” that requires no BFA but is magnitudes more expensive.

And the bayonet.

And the bayonet.

Will be retired.

Blanks are ivo of 4EFC’s The powder cuts the throat - so in the ideal world they die.
Run a Sims bolt for any FoF

Fixed is a bit of a misnomer, as you take them off to clean the barrel, and SSI (and all other .mil suppressor companies) has a bullet trap BFA can look a like, as well as a Sims ‘can’ for FoF.

Given there is no tactical situation to realistically remove the can, having a thread on non QD rifle/carbine can isn’t a bad thing.

Noooo!!! What about drill? Isn't that the vital ground?

As pusser as that is, its not without its merit. Rifle drill looks better with bayonets IMHO.

Blanks you can actually hear from more than 50m away are great.

100000 PSI for a 5.56 round.....??????

Holy crap.

I had a discussion about this with the ETQMS here at TEME about ammo/ballistics/etc with the new rifles coming, and basically we both agreed that going with a shorter barrel and standard NATO spec 5.56 62 gn C77 ammo is going to be a decrease in both ballistic and terminal performance.

We left our discussion with the point that we both hoped there would be new ammo coming with the new rifles.

I did not realize this was the path we were on - I was pondering improved terminal performance ammo like the OTM MK262 stuff, this is a whole different ball of wax.

Zipping out at 3500+ FPS from an 11-ish inch barrel? That's insane pressure - but ballistically it will be a much flatter trajectory making it easier to hit point targets without worrying as much about the drop of the bullet.

Almost like we're heading towards the old SPIW flechette performance with the speed and flat trajectories they were experimenting with back in the 60s.

There is nothing new under the sun.
