Thompson Center Cross-Slot Base Features The Thompson Center Cross-Slot Base is machined from steel and cut with a cross-slot pattern that accepts a wide range of ring styles giving the shooter flexibility when choosing an optic setup. Its matte black finish is durable enough to handle years of mounting and dismounting rings without showing significant wear. Designed to fit Contender barrels the base gives owners of this classic single-shot platform a dependable way to add a scope without aftermarket guesswork. The one-piece Weaver-style design keeps the base low profile while still providing a rock-solid mounting foundation. Installing the base is straightforward since it is purpose-built for the Contender s receiver contour requiring no additional fitting or gunsmithing. At just 1.75 pounds shipping weight the base itself adds negligible bulk to the rifle or pistol it is mounted on. Thompson Center backs the base with a manufacturer limited lifetime warranty reflecting confidence in its steel construction and finish. For Contender owners building out a hunting or target setup this cross-slot base is the factory-correct starting point for adding glass available for sale at GrabAGun.
