Thompson Center Cross-Slot Base Features The Thompson Center Cross-Slot Base is machined from steel and finished in a matte black coating that resists scratching and corrosion through repeated field use and recoil. Its cross-slot design gives shooters multiple positioning options for their scope rings allowing fine adjustment of eye relief to suit different scopes and shooter preferences. Purpose-built for the hard-recoiling nature of muzzleloader platforms this base is engineered to hold zero reliably shot after shot even under heavy charges. A one-piece Weaver-style design keeps the mounting system simple and secure without unnecessary complexity.

Installing quality glass on a muzzleloader significantly extends practical hunting range and a solid base is the foundation that makes that upgrade possible. Thompson Center has built a reputation for durable dependable muzzleloader hardware and this Cross-Slot Base continues that tradition. For hunters looking to mount a scope securely on their Encore-based muzzleloader this base is a straightforward reliable choice.
