The EGW Howa 1500/Weatherby Vanguard short-action scope base is a one-piece Picatinny rail system engineered for shooters who want rock-solid optic mounting without compromise. If you're running a Howa 1500 or Weatherby Vanguard short-action rifle and need the flexibility to swap scopes, adjust eye relief on the fly, or pair your gun with Picatinny or Weaver rings, this heavy-duty aluminum base delivers the precision and rigidity that matter downrange.
Built from extruded 7075 T6 aluminum, the EGW base is machined to MIL-STD 1913 specifications with cross-slots gauged to +/-.002" tolerance—the kind of tight engineering that keeps your zero stable through seasons of hunting or range work. The heavy-duty profile sits .100" lower than lightweight alternatives, positioning your optic closer to the bore for a cleaner sight picture and no unnecessary weight riding atop your rifle. Installation is straightforward: the base drills directly into your factory scope mount holes using the included socket head Torx screws and wrench. EGW recommends 20 inch-lbs of torque and a small amount of blue threadlocker for a permanent, repeatable connection.
Whether you're building a precision rifle, upgrading from factory rings, or just want the dependability of a name trusted by serious shooters, this base won't let you down. The modular Picatinny design means you're not locked into a single ring system—swap rings and scopes without reinstalling the base.
