The EGW Howa 1500/Weatherby Vanguard Short Action 20 MOA steel scope base is a one-piece Picatinny rail that bolts directly to your rifle's factory receiver holes—no drilling, tapping, or gunsmithing required. Built for shooters who want a rigid, repeatable foundation for their optic without the hassle of custom work, this mount brings precision-machined versatility to two of the most popular short-action platforms in hunting and precision shooting.
Machined from 4140 carbon steel and pre-hardened to Rc 35-35, this base delivers the stiffness you need for consistent accuracy. The 20 MOA (minute of angle) cant is built into the base itself, giving long-range hunters and shooters a ballistic advantage without eating into your scope's elevation adjustment range—especially valuable if you're pushing distance on game or paper. The full-width Picatinny slots are gauged to military standard MIL-STD 1913 specs to within .002 inch, so you can swap between standard Picatinny or Weaver rings without worrying about fit or repeatability.
EGW engineered the Heavy Duty profile .100 inch lower than their lightweight alternative, keeping your scope closer to the barrel's centerline for a lower sight line and improved cheek weld—a real advantage in the field. It's drilled to match Howa and Vanguard factory mount patterns, so installation is straightforward. The package includes socket-head Torx screws and wrench; EGW recommends 20 inch-pounds of torque and a small drop of blue threadlocker for long-term security.

Frequently Asked Questions
Will this base fit my Howa 1500 or Weatherby Vanguard Short Action?
Yes. The EGW mount is drilled to align with the factory scope mount holes on both Howa 1500 and Weatherby Vanguard Short Action receivers, so installation is straightforward—just bolt it down with the included Torx screws.
What's the advantage of the 20 MOA cant?
The 20 MOA angle is built into the base, tilting your scope upward and giving you extra elevation adjustment travel for long-range shooting. This is especially helpful if you're hunting or shooting at distance and don't want to burn through your scope's adjustment range just getting dialed in.
Can I use any Picatinny or Weaver rings on this base?
Yes. The Picatinny slots are machined to MIL-STD 1913 specification, so they accept standard Picatinny rings. The base is also compatible with Weaver-style rings, giving you flexibility in optic choice and ring selection.
What's in the box and how do I install it?
The mount comes with socket-head Torx screws and a wrench for installation. Remove your rifle's factory rings, bolt the EGW base to the receiver holes where your old mounts were, then attach your Picatinny rings and scope. EGW recommends torquing the fasteners to 20 inch-pounds and applying a small drop of blue threadlocker for security.
