If you haven't visited the website of the Remington Adaptive Combat Rifle, I strongly suggest you check this out. RemingtonMilitary.com Make sure you download their brochure, and also watch their 4 animated clips about how the rifle works. To me, this blows every other AR-15/variant out of the water. This gun will outperform any M16/variant, and will certainly outperform an M14 or Kalashnikov rifle. I want your thoughts. What do you think about the ACR? This is by far my favorite gun.
