The EGW Thompson Center Dimension 1-Piece Picatinny Base is a solid foundation for mounting optics on your Thompson Center Dimension rifle. This one-piece design brings rigidity and simplicity to your build—no fiddling with separate components or worrying about alignment. The zero-MOA configuration suits shooters who are mounting optics with integral adjustments or who prefer a direct drop onto flat-topped receivers. Since EGW machines these bases in-house and finishes them with tumbling, sand blasting, and Type II anodizing, you're getting a purpose-built accessory that holds up to field use.
The Picatinny cross slots run the entire length of the rail, giving you flexibility to position your scope rings (or other rail-mounted gear) exactly where you need them. That matters when you're trying to dial in eye relief or work around an existing accessory setup. The channel milled into the center of the base keeps weight down without sacrificing strength—and in many cases, it leaves clearance for factory iron sights if you want to keep them as a backup.
Installation is straightforward: clamp the base to your receiver using 20 inch-pounds of torque and secure it with a drop of blue Loctite. EGW recommends confirming your receiver's hole spacing matches their published specs before purchase, so take a moment to measure if you're swapping systems. This is the kind of no-nonsense, American-made mount that hunters and range shooters alike have relied on for years.
| Mounting System | Picatinny rail (full-length cross slots) |
| Cant | 0 MOA |
| Configuration | One-piece base |
| Platform | Thompson Center Dimension |
| Finish | Type II hard anodize |
| Installation Torque | 20 inch-pounds |
The lightened centerline channel may allow clearance for factory iron sights in many cases, though fitment can vary depending on your specific rifle's configuration. Verify clearance before installation.
EGW recommends applying 20 inch-pounds of torque to the mounting fasteners and using a small drop of blue Loctite to prevent loosening. Loctite is sold separately. Always confirm your receiver's hole spacing matches EGW's published dimensions before assembly.
One-piece designs eliminate the potential for misalignment between front and rear components, simplifying installation and delivering repeatable accuracy. A single rigid platform reduces points of failure and drift over time.
Yes—the full-length Picatinny cross slots accept any standard Picatinny-pattern ring or accessory, giving you flexibility in ring selection and positioning along the rail.
