The EGW T/C Venture & Compass Action scope base brings modern Picatinny rail mounting to your Thompson Center rifle without any gunsmithing. Built from precision-machined 6061 T6 aluminum, this one-piece base fits directly to your factory receiver holes—no drilling, no tapping required. Whether you're upgrading from iron sights or swapping optics, the standardized Picatinny slots let you adjust eye relief quickly and pair your rifle with virtually any modern scope ring setup.
EGW engineered this base to MIL-STD 1913 spec with cross-slots gauged to ±.002 inches, so your rings sit true every time. The lightweight tactical design includes a milled center channel that shaves weight without sacrificing rigidity. The base ships with socket head Torx screws and wrench for straightforward installation; EGW recommends 20 inch-pounds of torque and a small dab of blue Loctite to lock everything down.
If you run a Venture or Compass short action and want a clean, no-fuss way to mount glass—whether for hunting, range work, or precision shooting—this scope base gets you there fast. It's the kind of detail that turns a factory gun into a genuine hunting tool.
