Magazine fed 308, spent brass comes out the front so you can fire from either right or left shoulder, has an 18.1" long barrel and 26.1" overall length (both just barely legal), and is one sweet firing rifle. I've got to shoot one, twice, for several magazines. VERY well balanced with the bulk of the weight centered between your fore hand and the shoulder, and it literally centers on the pistol grip - perfectly centered mass there.
I'm saving up for one - I think it's about the best option for a 308 out there, save something needed for serious target shooting. I was putting together 2-3 MOA groups in my first magazine, and tightened up to 1.5 to 2 MOA on my second (4X scope was mounted). Plenty accurate for anything I'd ever need it for.
Besides, having such a compact rifle would be great when out hunting in thick underbrush - no more trying to handle a 42" long rifle!
