The EGW Howa 1500/Weatherby Vanguard Long Action 20 MOA scope base is a one-piece Picatinny rail system engineered for precision rifle shooters who want to mount quality glass without gunsmithing. Unlike factory two-piece bases, this single-rail design clamps directly to your rifle's receiver using the existing factory scope mount holes—no drilling, no tapping, no permanent modifications. The 20 MOA elevation built into the rail is ideal for hunters and long-range shooters running heavier magnum cartridges or pushing shots past 500 yards; that slope adds elevation adjustment capacity without maxing out your scope's internal turrets.
Built from 7075 T6 extruded aluminum, this is a heavy-duty mount that prioritizes rigidity and a lower mounting profile. The precision-machined Picatinny cross-slots are held to MIL-STD 1913 spec (±.002"), so it plays nicely with any standard Picatinny or Weaver scope rings. That modularity means you can swap rings and optics without re-zeroing your base, and you can fine-tune eye relief by sliding your rings along the rail. Socket head Torx screws and an included wrench make installation straightforward—EGW specs 20 inch-lbs of torque and a drop of blue loctite for a secure, repeatable fit.
If you're running a Howa 1500 or Weatherby Vanguard in long action and want to eliminate the compromise of factory bases while keeping your rifle action untouched, this is a smart, rigid platform that lets you build the optic setup that suits your hunt or range day.

| Material | 7075 T6 extruded aluminum |
| Picatinny Slot Tolerance | MIL-STD 1913 spec ±.002" |

Yes. The EGW base mounts directly to the existing factory scope mount holes on long-action Howa 1500 and Weatherby Vanguard receivers with no drilling or tapping required.
The 20 MOA elevation is built into the rail's angle, giving you extra adjustment range in your scope's turrets. It's most useful for long-range hunting and shooting, magnum cartridges, and situations where you're dialing elevation for shots beyond 500 yards. If you shoot standard rifle ranges under 300 yards, you likely won't use it, but it doesn't hurt to have it.
As long as your rings are Picatinny or Weaver-compatible, yes. The base accepts standard rings and lets you reposition them along the rail to dial in your ideal eye relief.
The base comes with socket head Torx screws and a hex wrench for installation. You'll need a torque wrench capable of measuring 20 inch-lbs for proper setup, and blue loctite is recommended to keep screws secure.
