EGW Guns Picatinny Scope Base Features The EGW Guns Picatinny Scope Base is machined from ultra rigid 6061-T6 extruded aluminum a material chosen for its strength to weight ratio and its ability to hold zero under the recoil of large frame revolver cartridges. The base is drilled to align directly with the factory scope mount holes already present on Smith and Wesson K L N and X frame revolvers so no drilling or tapping of the receiver is required during installation. Full width cross slots are gauged to MIL-STD 1913 specifications within plus or minus .002 inches ensuring Picatinny or Weaver rings seat securely and repeatably. A milled center channel on the lightweight tactical design trims unnecessary weight without sacrificing rigidity. Finished in a matte black finish the base blends cleanly with most revolver finishes while resisting glare that could interfere with sighting. Picatinny slot and rail spacing gives shooters the freedom to make fast adjustments to eye relief or swap scopes entirely without purchasing a new base. The package includes socket head screws and a wrench and EGW recommends 20 inch pounds of torque along with a drip of blue Loctite for a secure long term mount. Precision engineered for a no compromise fit this scope base is a reliable upgrade for revolver shooters available for sale at GrabAGun.
