Mine is a touch over 14 lbs. It's a .260 AI with a 29"+brake barrel, modified B&C stock, PTG bottom metal and 10 round Alpha AICS mag.
If I dont have a backpack, such as while antelope hunting, I use a backpack sling with the QD mounds I installed on the side of the stock. Otherwise, I take off the bipod and hold the barrel while the rifle is over my shoulder, or carry it in my arms. If I don't think I'm going to need it quickly, I attach it in my backpack which has a spot to strap in a rifle.
It might be a lot of weight, but with 20+ one shot kills on critters from antelope to elk ranging from 250-925 yards, its hard to grab any other rifle.
