What is the operation on that Vltor? The Remington system is just an upper; a hopeful choice to aid with the issues that have stemmed from the M4's gas system.
Apparently, it's a great deal similar to the operation system on that ACR....aka, the scar, the other ACR, the Massoud, and whatever other gun it operates like.
Truth be told, we don't need all the reliability in the world...with our grand count of 5 rounds, but it certainly seems like an interesting choice. Less polymer than the above systems, so I'm happy. Anyone catch a glimpse of the new Sig platforms?
