The EGW 20 MOA Picatinny Scope Base for Thompson/Center Encore (EGW part no. 46902) bolts onto your Encore frame and adds 20 MOA of built-in elevation correction for stretching a single-shot rifle or pistol out to longer range. Evolution Gun Works machines this base from 6061-T6 aluminum rather than casting it, finishing it in matte black to match most Encore barrels. The Picatinny-spec rail accepts any standard Picatinny ring or mount, so you’re not locked into a proprietary system. EGW includes the mounting hardware and a torque spec, so the install goes cleanly the first time.

Key Specifications

• Machined from 6061-T6 aluminum rather than cast, for a stronger, truer-fitting base.
• Finished in matte black to match most Encore barrels and cut glare.
• Measures 5.488 inches overall, spanning the top strap of the Encore frame.
• Uses a 0.838-inch center spread between mounting holes, matched to the Encore’s factory hole pattern.
• Cut to the Picatinny/MIL-STD-1913 rail spec, so it accepts standard Picatinny rings or mounts.

• EGW recommends torquing screws to 20 in-lbs with blue Loctite for a base that won’t walk under recoil.

Frequently Asked Questions

Does this base fit the Thompson/Center Encore? Yes, it’s purpose-built for the T/C Encore frame and bolts on using the factory hole pattern.

Are scope rings included? No, this is the base only; pick up a set of Picatinny rings separately to complete the mount.

How much elevation correction does the 20 MOA add? The built-in 20 MOA cant gives your scope extra downward adjustment range, useful for stretching out to longer distances before you run out of elevation.
