The Weaver Top Mount Scope Base, TCA Thunderhawk (brand part no. 48111) is a one-piece scope base built to fit the Thompson/Center Arms Thunderhawk muzzleloader. Weaver machines each base to tight tolerances for a custom fit to the receiver, and the aluminum construction offers plenty of strength for rings to clamp down without flexing under recoil. The base carries Weaver’s rock-solid cross-lock design, which is compatible with a wide range of Weaver-style rings rather than locking you into one ring manufacturer. Mounting a scope on a Thunderhawk starts here, and the base is a direct bolt-to-receiver fit with no gunsmithing required.
