I picked up (not bought, like lifted up, haha) a Daniel Defense DDM4V11 a few months ago and can't get it out of my head. It is SOOOOO light! It got the wheels in my head turning. My current AR-15 weights 8.4 pounds with a Sparc 2 on it. I put the weight of the components of my build into a spread sheet, and compared it to light weight upgrade options. I figure that I can shave off a pound and a half even after upgrading to a heavier Eotech. What does your AR-15 weigh?
