EGW Guns Picatinny Scope Base Features The EGW Guns Picatinny Scope Base is machined from 6061-T6 extruded aluminum a material selected for its durability and resistance to flexing under recoil. Full-width cross-slots are gauged to MIL-STD 1913 specs within plus or minus .002 inches giving shooters a precise repeatable fit for Picatinny or Weaver scope rings. Because the base is drilled to match the factory scope mount holes on the Thompson Center Encore no drilling or tapping of the receiver is required. Its 0 MOA rating makes it a straightforward choice for shooters not needing elevation compensation built into the base itself. At a 5.488 inch overall length and a 0.838 inch center spread the base is sized to match the Encore s specific mounting hole pattern for a precise drop-in fit. The matte black finish keeps glare down in the field which matters for hunters glassing game in bright conditions. EGW includes hex head screws and a wrench for installation and recommends 20 inch pounds of torque along with a drop of blue threadlocker for a secure lasting mount. This base gives Encore owners a reliable path to a huge range of Picatinny-compatible optics for sale at GrabAGun.
