The Thompson Center 1-Piece Scope Mount Base for pistols or rifles. Mounts directly on the barrel of T/C Encore Omega 50. The base is cut from solid steel and then machined to the closest of tolerances to ensure a strong and stable platform. These bases are built and constructed to last you a lifetime. The heavy-duty construction prevents the scope from moving even with the heaviest of recoils. The highly durable steel also allows for windage adjustment that is integral to getting a precise sighting on your scope.
