Description
This is EGW's Steel HD scope base built for Howa 1500 and Weatherby Vanguard short action receivers, and it's about as solid a foundation as you can bolt onto a bolt gun. Machined from one piece of 4140 carbon steel and finished in Parkerized black, it ties the front and rear of the receiver together into a single rigid platform. That one-piece design is a big deal for repeatable accuracy, since it keeps everything locked in alignment instead of relying on two separate bases that can shift independently.
Why the Steel HD Build Matters
The HD line sits .100" lower than EGW's lightweight mounts, which pulls your optic closer to the barrel centerline for a cleaner cheek weld and a steadier hold. The cross-slots are cut to MIL-STD 1913 spec within a couple thousandths, so your rings seat exactly where they should and you get real flexibility to slide the scope fore and aft for proper eye relief. It takes any standard Picatinny or Weaver ring, and it's quick-disconnect ring compatible if you run a setup you like to pull on and off.
Fit and the 20 MOA Angle
This base drops onto the factory scope mount holes on your Howa 1500 or Weatherby Vanguard short action, so there's no drilling or tapping involved. It covers the common short action chamberings like .223 Rem, .22-250, .243 Win, 6.5 Creedmoor, 7mm Rem Mag, and .308 Win. The 20 MOA built-in cant tilts your optic forward, banking extra elevation travel so you can dial for distance without running out of adjustment. If most of your shooting lives inside 500 yards a 0 MOA base is plenty, but if you're stretching toward 1000 the 20 MOA earns its keep. It's worth noting this one will not fit the Howa 1500 Superlite.
Install and Setup
Mounting is straightforward with the included Torx hardware. EGW recommends torquing the screws to 20 inch-pounds with a drop of blue thread locker, and with a 20 MOA base a 200-yard zero is a good starting point before you start dialing for longer shots.

Frequently Asked Questions
Will this Steel HD rail fit my Howa 1500 and Weatherby Vanguard?
Yes, it's made specifically for Howa 1500 and Weatherby Vanguard short action receivers and drops onto the factory scope mount holes with no drilling or tapping. It also works on older Ruger M77s with radiused receivers. Just note it will not fit the Howa 1500 Superlite.
Should I get the 20 MOA or the 0 MOA version?
The 20 MOA tilts your optic forward to bank extra upward elevation travel, which helps when you're dialing out toward 1000 yards. If most of your shooting stays inside 500 yards, a 0 MOA base is all you need. With the 20 MOA rail, zeroing at 200 yards is a solid starting point.
What rings does this base work with?
It accepts any standard Picatinny or Weaver scope rings, so you've got plenty of options for ring height and brand. It's also quick-disconnect ring compatible if you like to pull your optic on and off. The cross-slots are cut to MIL-STD 1913 spec for a precise fit.
How should I install it and what torque do I use?
Mounting is simple using the included Torx screws and wrench. EGW recommends torquing the screws to 20 inch-pounds with a drop of blue thread locker to keep everything tight under recoil. Snug it down evenly and you're set to mount your rings.
