I see arguments for both sides. But the new gun is definitely a pig!
You’re correct. They were looking to replace the 556 with the 6.8spc. In fact it was being used by special forces. Actually it’s my favorite round as I’ve put together a few rifles in that caliber. However this is the 6.8 Fury. It is based off of a .308 case and is necked down for a .277 projectile. Since it is based off of the .308, I think that it will only be a matter of time before a barrel manufacturer makes a 6.8 Fury barrel for the AR10.I was hearing stories from a colleague that the military contractors were using the 6.8 SPC around 2007 and it will replace the 5.56 round. The 6.8 definitely is a better choice. I know some gun magazines tried to make it sound like it was using a .270 Winchester in an AR platform.
My friend who was in Vietnam went there with his M-14. He was issued the M-16. He hated the rifle. He called it the Mattel rifle. He said the M-16 killed many soldiers because they didn’t provide the necessary cleaning kits or training. It was lighter and carried more ammunition compared to the M-14. He did have experience in combat. He loved the 12 gauge the best followed by the 1911 .45 pistol. Most encounters were CQC. He never owned an AR-15 rifle from his experience with the M-16.The 6.8mm is a step, in the right direction and, in my mind, long overdue. When I was in the Army (late '60s~early '70s), we were in the process of changing, from the M-14, to the M-16. With the M-14, we didn't have trouble consistently hitting/eliminating targets, out to 1,000 yards. With the early version M-16s, it was hard to be accurate, out to 200 yards and, when the target was hit, with the centerfire .22 round of the M-16 (a/k/a "the mouse gun" or the "Matty Mattel special"), the target didn't receive the hydrostatic shock/stopping power of the 7.62mmx51 (.30 caliber) round of the M-14. Were we able to carry fewer rounds, for the 14, because of weight and bulk? Yes but we didn't need as many rounds, as with the 16, to stop anything. With the 14: 1 round, 1 hit, 1 down and out. 6.8mmx51 = good FIRST move. It's not just because the AK always works, under adverse conditions and can be operated by a monkey, that it's still so popular. That 7.62mmx39 (.30 cal) round has real stopping power.
I feel the same, about the 9mm vs the .45 ACP.
My 2 cents. I know some will disagree.
