The EGW Savage B-Mag scope base gives you a modern Picatinny rail mounting system for your Savage B-Mag shotgun—no gunsmithing required. Built from 6061 T6 aluminum and drilled to match your factory scope mount holes, this one-piece base transforms your receiver into a flexible platform for optics changes without the hassle of drilling and tapping. Whether you're swapping between magnified scopes, red dots, or other Picatinny-compatible rings, you get the speed and simplicity of slot-and-rail design with the rigidity of precision-machined aluminum.
The Picatinny slots are gauged to MIL-STD 1913 specifications (±.002") for rock-solid repeatability. EGW machines a center channel into the tactical design to shed weight without sacrificing strength—a detail that matters on shotguns you carry all day. The base accepts both Picatinny and Weaver scope rings, so you're not locked into one ring style or another. Installation is straightforward: the included socket head Torx screws and wrench get the job done. EGW recommends 20 inch-pounds of torque and a drop of blue Loctite during setup.
If you hunt with a Savage B-Mag and want to run modern optics without permanent modifications, this base gives you the flexibility to dial in eye relief, switch between scopes, or upgrade to newer glass down the road. It's built to stay put through recoil and seasons in the field.
