So I watched the 2 YouTube videos from ShotShow on the Roam lightweight .308's (Military Arms Channel and AR15.com). Then nothing and nothing for over 6 months. Now YouTube hog hunting channel "Texas JAGD" has 2 videos using their 5.6 pound Ultralight and (shows the gun on a scale). I called Roam to learn what I could and it seems real to me. After the first JAGD video I spoke with a buddy who works daily with magnesium aerospace parts about the weight delta and he assured me magnesium is 1/3 lighter than aluminum and the engine gearboxes he deals with are plenty strong. Have any of you shot one of these lightweight Roam rifles before? If so any thoughts? Because lugging around my DPMS Gen 1 (Roam is DPMS compatible) is getting old. Thanks for any response.
