I would not expect that to be possible.To throw a bullet likely nearly twice as heavy at the typical 5.56mm projectile significantly further, with higher energy is going to require more propellant and larger casing. Make no mistake, they're not talking about upgrading to 6.8 SPC, it will be a whole new intermediate cartridge. I would expect it to be relatively similar to the dimensions of the US Army Marksmanship Unit's .264 USA (6.5mm) round. They needed to use new rifles, the AR-12, based off the AR-10 platform. Of course, they could be focused on adopting a 6.8mm bullet fired from a cased telescoped round, which would likely not be compatible with any conventional 5.56mm firearm currently fielded.The US Army is testing a 6.8mm round to replace the 5.56mm cartridge. They are trying to lighten the case as well. It will be interesting to see what they come up with.
So Long, 5.56: The Army Is Testing A Bigger Bullet For Its SAW And Carbine Replacements
New Zealand has purchased the the New Carbines made by Lewis machine tools to replace the Steyr will they be able to be chambered to take the 6.8mm round.?
