EGW Guns Picatinny Scope Base Features The EGW Guns Picatinny Scope Base is machined from 6061-T6 extruded aluminum a material chosen for its strength to weight ratio and long-term durability under recoil. Built in a 20 MOA configuration the base compensates for bullet drop at extended range letting shooters dial in more usable elevation adjustment from their scope before running out of internal travel. This is particularly valuable on a Thompson Center Encore set up for long range hunting or precision shooting applications. The matte black finish resists glare in the field and matches typical firearm finishes for a clean factory-like appearance. Designed specifically for the Thompson Center Encore the base measures 5.488 inches overall with a 0.838 inch center spread between the middle mounting holes ensuring a precise direct fit to the receiver. Mounting hardware including hex head screws and a wrench ships with the base for straightforward installation. EGW recommends torquing the screws to 20 inch pounds with a drop of blue Loctite for a secure vibration-resistant mount. Made in the USA this scope base gives Encore owners a reliable Picatinny platform for mounting long range optics.
