6.8mm

Interesting news in the world of firearms (if you follow that kind of stuff). True Velocity’s 6.8x51mm polymer case turns out to work quite well with legacy firearms (machine guns and SAWs), simply by switching the barrel. For those unfamiliar, the 7.62x51mm (which is the NATO dimensions) has the same length as the new 6.8mm, so they fit the chambers quite nicely. https://www.tactical-life.com/news/us-army-6-8mm-weapon-systems/

Not saying I called it, but does anyone remember the caliber used in the Militia issue rifle on Hayek? Hint, hint: 6.8mm, but longer than the 6.8SPC.

    1. Nope – better. Look at the characteristics – 6.8x51mm vs. 6.5x39mm. The 6.5 could fit the M-4 platform, but not the LMG or SAW platforms that utilized 7.62×51. While the 6.5 outperforms the 5.56 for distance, I don’t believe it’ll outperform the 6.8 (which also utilizes a polymer case which is a lot lighter than brass).

    1. Not the 6.8 SPC – the new round is likely a necked down 7.62 x 51 (as the length is identical). The 6.8 SPC was designed to fit into the M4 platform due to it’s better distance performance out of the short barrel. The 6.8x51mm is more designed for larger systems (think M60 for those of us that old).
