US Army Considers Adopting an Interim Battle Rifle in 7.62NATO: eventually adopt 6.5

[stanc]

So you have confirmation the M249's are being turned in? Not kept in inventory? :-)

I didn't say the M249s were not being kept in the inventory. I said that the rifle squad's M249s were being replaced by M27s.
As for confirmation, there were official announcements at the time. But, all I could find in a quick search today is this article:

The M27 IAR is being phased in to replace the M249 Squad Automatic Weapon... http://www.2ndmardiv.marines.mil/News/Ne...-m249-saw/

Correct, PKM, rather. Which on paper, may be ballistically slightly faster than the 7.62x51, but in the real world are effectively equal. Except the PKM has sights to 1500m and on paper an effective range of 3800m, yet the 240B effective range (by us) is 1100M. So what's the difference?

:confused: I said the M240B and PKM are equal. You said the M240B outranges the PKM "in pretty much every situation."

So you want to compare a crew served against a squad weapon???

What I want is not the issue. Enemy 7.62x54 rifles and machine guns outrange 5.56x45 carbines and machine guns.
That range overmatch is what originally prompted people to advocate a 7.62x51 rifle to replace the 5.56x45 carbine.

Not really going to debate this... if you really think there is appetite to do such a large change you are far more optimistic than most of us.

:confused: I never said there is an "appetite" to do such a large change.

I said that such a change has been done many times in the past, so there is no reason to think that it could not be done again, and without being a "logistical nightmare."
