What is the purpose of the hybrid cartridge metal base?

Higher pressure. 80,000 PSI. This apparently can’t be achieved using brass alone and a steel base is required to check expansion at the base of the cartridge.

Going to be a barrel burner at those pressures, can't be good for throat and gas port erosion.

5.56 is not an effective round against people during CQB. 


The ballistics experts in the MSM have told us its the most deadliest round evah evah, designed to kill they say.

Anyway thats bullshite but it IS an effective CQB round, as compared to what? A 9MM, 45ACB?

Clames pretty much nailed it. Keep what you got or go back to real battle rifles.

I understand the ammo carrying capacity thing but it seems like if you want more horsepower, you could just go back to issuing M14's or AR10's or something and keep the ammo common.

Yall ever seen pentagon wars? That's what I picture in my head whenever I hear of JSOC wanting some new toys

IDK man when you have to put 2 or 3 in a guy to actually stop him, then to me it’s not that effective. 5.56 is too light of a round for people.

People act like you’re not getting shot at when you are shooting people. You want a round that has enough energy to stop an enemy combatant with one round to the mid to upper torso.

There are several million dead people across the planet that disagree with that

An 80,000 PSI “universal” FMJ military round just sounds like a bad idea.

High rate of weapon component wear and failure.
High cost of procurement.
Increase in recoil to levels equating a true battle rifle round.
Over penetration in CQB settings and other close-in engagements.

But I guess that’s why I don’t get paid the big bucks-but someone else is and will.

Id be worried about extraction problems and general reliability.

Could you imagine the muzzle blast from a carbine barrel

Oh yeah-I forgot to mention they are proclaiming 3,000 FPS for a 135 gr. bullet out of a 16” carbine barrel.

I don't know anything about the 6.8 cartridge that can't be googled, but I do know that the Sig offering to the competition looks like a badass gun. I hope they put out a civilian version down the road because I'd definitely get one.

The one on top is Sig's offering to replace the M4 and the bottom is to replace the M249 SAW.

I don’t know why we don’t just use .308 or 30-06

30-06 Springfield was widely used in WW2 in M1 Garland, Springfield sniper rifles, and the BAR

Seemed to do just fine as a universal round for many different types of rifles

Thats what I dont understand. New platform? Sure, the M14 is what you have and its a huge ancient outdated piece. New caliber that will eat barrels? Don't make sense to me.

It's basically a modified MCX with a side charger added

Are there suppressors out there that can hold up to full auto rifle firing? Seems i remember them needing to be taken apart and cleaned pretty often.

The Ar10 platform is superior to the m14 and could be implemented with minimal retraining of the troops. Its not overly heavy and is inherently accurate.

I think they're going for a revolution in arms and not evolution here. In firearms that rarely happens successfully.

There are. Putting one on every rifle seems like a pipe dream, though.



If they did adopt it, I wonder how it would affect NATO. I assume they'd just keep what they have rather than having to completely re-arm.

Seems like suppressors would be dirt cheap to the military. Why woulsbt they put them on everything.
