Description
If you're building out a Remington 700 long action for distance work, the rail you pick matters just as much as the glass sitting on top of it. MDT's 20 MOA Picatinny base gives you a solid, repeatable foundation for your optic, and the built-in forward cant frees up more of your scope's internal elevation so you can dial further without running out of adjustment. It's a clean, no-nonsense piece that does exactly what a good base should.
What the MDT 700 LA Base Brings to the Bench
This rail is CNC machined from 6061-T6 aircraft grade aluminum and finished with a mil-spec Type III hard anodize, so it shrugs off the knocks and weather that come with real hunting and range time. The underside is profiled to sit flush against the receiver and match the geometry of the ejection port, which keeps everything low and tidy. It also carries an integrated recoil lug, giving the setup extra bite against the pounding of heavier long-action calibers. The slots are cut to MIL-STD-1913 and STANAG 4694 spec, so your rings and optics mount up without any guesswork.
Why 20 MOA Makes Sense
The 20 MOA incline is the go-to standard for hunters, PRS competitors, and anyone stretching their rifle out past comfortable zero range. By tilting the scope slightly forward, the base shifts more of your elevation travel toward the far end, so you've got the adjustment on tap when the target's way out there. Just keep in mind the actual amount of extra elevation you gain depends on your particular scope's internal range.
Fit and Mounting on Your Remington 700
This is the long action version, cut specifically for the Remington 700 LA footprint and custom clones built on that pattern. It's a one-piece rail and ships with #6-48 Torx mounting screws, with the base also drilled to accept #8-40 screws if you want to step up the hardware. The contoured profile keeps edges smooth so nothing snags on your gear in the field.

Frequently Asked Questions
Will this MDT base fit my Remington 700 long action receiver?
Yes, this rail is cut specifically for the Remington 700 long action footprint and custom actions built as 700 clones. The underside is profiled to sit flush on the receiver and match the ejection port geometry. Make sure your receiver is the long action pattern rather than a short action before ordering.
What does the 20 MOA on this scope base actually do?
The 20 MOA incline tilts your optic slightly forward, shifting your available elevation travel toward the far end so you can dial for longer distances. It's the standard choice for hunting, PRS, and general long-range shooting. The exact amount of extra adjustment you gain will depend on your scope's internal elevation range.
Does the MDT 700 LA base come with mounting screws?
Yes, it ships with #6-48 Torx screws for mounting to your receiver. The base is also drilled to accommodate #8-40 screws if you prefer to run heavier hardware. You'll still need scope rings to attach your optic to the Picatinny rail.
Does this rail include a recoil lug?
It does. MDT integrated a recoil lug into the underside profile of this base, which helps anchor the rail and your optic against the recoil of heavier long-action calibers. That extra support helps keep your zero consistent over time.
