Tony Williams Wrote:I really don't see the US Army approving anything in other than 5.56mm, given the huge amount of effort and publicity behind the M855A1 and the fact that their own in-house study of carbine calibres (which came down in favour of the 6.5-7mm range) has been withdrawn from further discussion after the initial presentation.I'm sure you're right, Tony. It's just that the carbine competition seems like it would be the perfect opportunity for the Army to see a side-by-side comparison of 6.5 Grendel (and 6.8 SPC) with 5.56 NATO.
