Description
If you run a Howa 1500 in a long action chambering and you want to stretch the legs on your optic, this MDT scope base is one of the cleaner ways to do it. It is a one-piece Picatinny rail cut specifically for the Howa 1500 long action footprint, so it sits flush on the receiver and lines up with the ejection port the way it should. The 20 MOA built-in incline gives your scope more usable elevation travel, which matters a lot when you start dialing for longer shots and don't want to run out of adjustment inside the turret.
Why the MDT Howa 1500 Rail Earns Its Spot
MDT machines these bases from 6061-T6 aircraft grade aluminum and finishes them with a Mil-Spec hard anodize, so you get a rail that stays put under recoil and shrugs off the usual field abuse. The underside is profiled to mount flush against the Howa receiver and follow the geometry of the ejection port, which keeps everything low and tidy. The rail follows MIL-STD-1913 and STANAG 4694 spec, so it plays nice with any standard Picatinny rings you already own.
Built Around the 20 MOA Advantage
That 20 MOA cant is the sweet spot for most hunting and long-range setups. By tilting the optic forward, you free up a chunk of elevation adjustment that would otherwise get eaten just getting to your zero. For folks shooting the Howa 1500 at real distance or dabbling in precision rifle work, that extra room pays off when the come-ups start adding up.
Mounting Up Your Howa 1500
The rail ships with the hardware you need to get it on the gun, including #6-48 Torx screws, and the base is drilled to accept #8-40 screws if you want to step up to beefier fasteners for heavier recoiling builds. It is a straightforward install for anyone comfortable mounting their own optic, and the contoured edges keep it from snagging on gear or clothing in the field.

Frequently Asked Questions
Will this scope base fit my Howa 1500?
This rail is cut specifically for the Howa 1500 long action receiver. If your Howa is a short action model, you'll want the short action version instead, since the hole spacing and receiver footprint differ between the two.
What does the 20 MOA cant actually do for me?
The 20 MOA built-in incline tilts your optic slightly forward, which hands you more usable elevation adjustment inside the scope's turret. That extra travel is what lets you dial up for longer shots without bottoming out your adjustment, so it's a popular choice for hunting at distance and precision rifle work.
Does this base work with standard Picatinny rings?
Yes. It's machined to MIL-STD-1913 and STANAG 4694 spec, so any standard Picatinny rings will clamp right on. That gives you plenty of freedom to run the rings and spacing that match your optic.
Does it come with everything I need to mount it?
The base ships with #6-48 Torx screws to fasten it to the receiver. The rail is also drilled to accept #8-40 screws if you'd rather run heavier fasteners for a hard-recoiling build. You'll just need your own rings and a torque driver to finish the install.
