The EGW Thompson Center Venture & Compass long action scope bases provide the versatility of a one-piece picatinny scope rail for your shotgun, eliminating the requirement for drilling or tapping. These bases are precision-machined from extruded aluminum and feature picatinny slot-and-rail spacing, allowing for quick and easy adjustments to eye relief, thereby offering significant flexibility in scope selection. They are pre-drilled to align with the factory scope mount holes on the firearm's receiver and are compatible with both picatinny and weaver scope rings. The lightweight tactical mounts include a milled center channel to reduce weight. The full-width cross-slots are manufactured to MIL-STD 1913 specifications with a tolerance of +/-0.002 inches. Constructed from ultra-rigid, extruded 6061-T6 aluminum, the package includes socket head Torx screws and a wrench. EGW recommends applying 20 in-lb of torque and a drop of blue Loctite for secure mounting.
