I think the 550 series of rifles are SIG only, no Sauer.
I really don't favor those new and "exciting" rounds out today like the 6.8mm, I don't see what is so bad about what we have. We have the .50 BMG when we want to touch someone at a mile, we have a .300 Win Mag when we want to down someone at 1000 yards, we have a .308 Winchester for when we need to touch someone at 500-900 yards. We have a .223 Remington when we want to fight at up to 300 yards and at CQB. And we have multiple pistol caliber handguns and submachine guns at close range. I really think we have the basics covered.
