Dave: I don't recall the exact weight of the Lonewolf stock (Summit), but average advertised weight is right at one pound. My Colt Lite weighs 6 lb. 10 oz. with Vari X III 3.5-10 x 40 scope & mount. My ULA weighs 6 lb. 12 oz. with the same scope and Talley mount. The Colt is 2" longer with Answer muzzle break.
