In my opinion...the momentum behind the 5.56 is so great, the average GI is going to be toting one for the next 25 years or more. To many people in high places think if it ain't broke...and so forth.
There is a good move afoot to re-introduce the 7.62x51 on a limited basis.
The bean-counters see the 6.8 and others as a logistics nightmare...while it sound like a good compromise...how many generals do you know that are good at compromising?
Personally, I don't see it happening. The resistance is too great Old farts like me remember the M14 fondly, new troops LOVE their 16's and M4's for the most part.
I like the AR platform, mine shoots great, it is a hell of a package, has been loved, cussed and discussed for 60 years.
Do you guys really think this administration or the next is going to spring for 500,000 new rifles and ammo? No matter how many of our troops fall?
If a miracle rifle and ammo became available, and I am not saying there is not one already available, our government loves $$$ more than troops. Ain't gonna happen.
I would love to be wrong on this...
