The EGW Savage Mark II scope base with 1-3/8" ejection port is a one-piece Picatinny rail designed to convert your Savage shotgun's factory receiver into a modern optics-ready platform—without drilling or tapping. If you're running a tactical shotgun or want to add glass to a gun that wasn't originally set up for it, this base lets you do that using the existing factory scope mount holes. It's machined from 6061-T6 aluminum and engineered to MIL-STD 1913 specs, so it'll play nice with any standard Picatinny or Weaver scope rings you have on hand.
The design centers around flexibility. The one-piece rail gives you freedom to dial in eye relief exactly where you need it, and the milled center channel keeps weight down without sacrificing rigidity. Installation is straightforward—the base drops into the factory holes, you torque it down with the included Torx screws, and you're ready to mount your optic. EGW recommends 20 inch-pounds of torque and a small amount of blue Loctite to keep things locked in place during hard use.
Whether you're setting up a home defense shotgun, a turkey gun with an electronic sight, or a competition gun that needs a red dot or low-power scope, this Savage Mark II base removes the guesswork and the gunsmith bill. It's a straightforward solution for bringing a classic receiver into the modern optics world.
