Normally I'd suggest a 15" JP VTAC rail, but only if you were sticking to killing paper. Since you want to hunt too, that means you'll be humpin' the rifle all over. Then I suggest the Apex CNC rifle length. The Apex CNC will give you plenty of barrel protection and is very light weight. You can add rails if your wish, or just stick to the cylindrical look. Personally I suggest Magpul MOE polymer rails, if you ever need them. You can put rails at 12, 1, 3, 6, 9, and 11 o clock. It also comes with preinstalled QD holes at both ends of the receiver. If you jump on the list now, they are taking pre-orders for the upcoming 15" free float system. www.apexcncmachine.com
