However, they developed the AR10 and AR15 to meet military requirements. Since 6.5 Grendel is neither a .30 caliber, full-power cartridge, nor a small caliber, high-velocity round, it would not have met the military requirements for either the AR10 or AR15, I just don't see those guys investing time and $$$ into developing a 6.5 G rifle.
LRRPF52 Wrote:Brits would have liked it too.Yeah, I think they might have. The 6.5 Grendel looks almost like a scaled-down .280 British, and both rounds shared the same design philosophy.
