Army picks SIG to produce Next Generation Squad Weapon

[JPB]

Cool that they got the updated steel magazine.

And the forward assist delete, and the new rail front end. Mine's now a limited edition collectors item!

I wish that YouTubers would give it a rest with posting click-baity videos which imply that they actually have MILSPEC 6.8x51 ammo when they just have the low pressure, brass cased, .277 Fury ammo that isn't even close to being in the same league, yet they seem to either be under the impression that the difference is the same as .223 Remington to 5.56x45 NATO, or at least they deally hope that the average viewer is.

Oh well, at least it isn't as asinine as when Military Arms Channel used a Bolt Action Rifle Chambered in 6.5 Creedmore and tested it against body armor as if it were a perfect analog to 6.8x51 out of a SIG MCX Spear.

Well, at least in the GT video, he had the hybrid case ammo loaded up to higher than standard pressure. (unless I was completely misunderstanding what they had) Like I said, still not the best for testing use, but not as bad as MAC or some of the early videos.

“Standard” and”civilian” pressures are 80k psi. I think logic can reveal why we don’t see much of that commercially.

Isn't there going to be a downloaded round that the military will use for training?

Unboxing their new rifles. Infantry privates, 1st Brigade, 101st Airborne Division.

I've read most of your posts in this thread.

How is the Army going to train individuals to effectively shoot this system? (I am assuming these rifles are all coming with the fancy McFancy scopes.)

Are they performing well so far?

They're just starting.

I’ve heard that, but don’t know if it’s true. My point was that the SAAMI spec for max pressure (or max average…don’t remember?) of .277 Fury is 80kpsi. Just wanted to clear up that any civilian ammo can also be full-flavor, potentially, because that seems to be a common misconception. Xcaliber barrels has a warning about this, but I suspect most companies aren’t going to sell a complete rifle that can’t handle at least some of the 80kpsi stuff for liability reasons, nor are they going to tell potential buyers to only shoot handloads in order to stay under 55kpsi or whatever.

It’s also worth noting that this is a new proprietary cartridge that exists roughly halfway between .264 and .284, but uses similar or same case geometry as 7-08 and .260. The obsession with splitting those hairs could have been for monetary reasons, or safety ones. Because there is nothing this cartridge can do that those couldn’t have, with the same pressure ceiling. But .270-08 previously only existed as a (promising) wildcat. Even if we take the requirements at face value and attribute neither incompetence nor malice in that direction, there was never really a need for completely different dimensions than already exist for other cartridges, but there may be a practical need, if indeed this much power is required for future combat engagements.

Saint John was there (from SIG).

Mike did confirm that barrels are DONE-ZO by 10k rounds. Not sure how many MOA that is.... sounds like a lot more than the 2.5 they all are supposed to start at.

Puts to bed the earlier bragging I heard from some that the barrels would "easily last 10k rds".

Still interested to see what SIG is using to get to 10k. I suspect it's a lined barrel (a la 240/M2).

I remember reading when this first started that the Army chose .277 because they found it was the "perfect" caliber for a combat rifle after their testing. Why is it better than a 6.5 or 7mm bullet? Who knows.

I read they are using "normal" brass ammo for training. This coincides with Sinister's lament that the scopes are set up only for the high pressure ammo earlier in the thread.
