Chad Dixon at Long Rifles Inc in SD as an alternative. Incredible quality and range of work and he's done plenty of T3s. My .300 Win Mag is arriving from him this week with an integrated brake, Rem style recoil lug and a Bartlein barrel. Quick work and very good communications and customer service.
