It seems the Army does not agree.

Yes, it's just my opinion, not the US Army opinion.

Of course, I can be wrong, but I really don't think that the US Army will spend 2.7 billions of USD to buy 250,000 rifle optics.

It's not as if they would have to buy a full supply plus an equal number of spares all at once. 

A portion of the total is to be acquired each year, so the cost would be spread out over time.

       How many NGSWs are being ordered?

I think it is quite possible that some personnel -- medics and engineers, for example -- may not have the M157 optic.

But, it really does not seem logical to me that any members of the rifle squad would not be equipped with the M157.

Probably try to give M157 to everyone using 6.8; but I wouldn't be surprised if an ACOG or red dot/magnifier combo becomes an issue item.

Of course, M157 was also described as "weapon agnostic", implying at least some were considering mounting them on other guns. 

assuming a BC of .200 for 762nato, whats the BC of 6.8? .250?

and what about MK262, is it on par with 762?

whats the BC of 6.8, is it higher than .200?

also i think they should have gone with a 6.5@ 2400ft lbs. it wuold match the 6.8 at long range

New high BC 25cal bullets are now appearing 

We might jet see .25cal gaining traction in shooting sports

The BC of the military EPR bullet is unknown, but the BC of the 135 gr FMJ "training practice" bullet is above 0.24 (C7), so already equivalent to the .308" 175 gr Sierra MatchKing.

This "reduced power, low recoil, training round", is already delivering a better trajectory from a 13.5" carbine than the M118LR fired from a 20" barrel...

Came across this on Twitter, debated wether this was NGSW or Shell Shock related. BAE seems to also have developed a specialized steel case design, possibly capable of higher (ngswish) pressures, and likely offering weight savings as well.

There reportedly is a weight savings, but the 5.56 / 7.62 ammo is not loaded to higher pressures.

But BAE may not be still pursuing this.  There is nothing on their site, and the article is 4 years old.

Looks like BAE may have changed to a one-piece steel case.  The article below is from 2 years ago.
