The EGW T/C Venture & Compass Action 20 MOA scope base gives Thompson Center rifle shooters a modern, modular mounting solution without the gunsmith work. This one-piece Picatinny rail mounts directly to your receiver's factory holes—no drilling, no tapping required. It's the fastest way to add versatility to your T/C rifle, letting you dial in perfect eye relief and swap optics whenever your hunting or range mission changes.
Built from 6061 T6 aluminum and precision-machined to mil-spec tolerances (±.002"), this mount is light, rigid, and built to last. The full-width Picatinny slots accept any standard Picatinny or Weaver rings, so you're not locked into a single ring design. The milled center channel keeps weight to a minimum without compromising strength—important when you're glassing all day or humping into the backcountry. Everything you need comes in the box: socket head Torx screws and the wrench to install them.
Setup is straightforward: mount it to your receiver holes, torque the fasteners to 20 inch-pounds, add a drop of blue Loctite, and you're ready to ring in glass. Whether you're running a lightweight hunting scope or a precision long-range optic, this base gives you the flexibility to choose the right tool for the job without buying a new rifle.
