bg: I suggest you try an ultralight AR, either in .223 or in 6.8 SPC. My latest build is a modern sporting rifle (i.e., designed for deer/pig hunting) chambered for the 6.8. Using the lightest components such as a pencil barrel, Smoke Composites buttstock/buffer tube, Bravo Company KMR10 handguard, titanium carrier with adjustable gas, and a few other lightweight goodies, it turned out to be 4 lbs, 7 oz with iron sights and no magazine. With a Leupold ultralight scope, a sling and a short mag with 3 rounds of Barnes 95 grainers, total weight is 5 lbs, 11 oz. IMO, its an amazing piece, so light it feels like a toy, but chambered for a credible game-getting round. - CW
