Description
This EGW base turns the top of your Winchester Model 70 short action into a solid, full-length Picatinny platform. It's machined in-house from domestic 6061-T6 extruded aluminum, then tumbled, sandblasted, and finished in matte black Type II anodizing for a durable, no-glare surface that holds up season after season. The real draw here is the 20 MOA cant, which angles the rail forward to give you extra elevation travel in your scope so you can dial farther out without running out of adjustment.
Why the 20 MOA Cant Matters on a Model 70
That built-in slope is what sets this version apart from the flat 0 MOA base. EGW suggests the 20 MOA rail for shooting in the 500 to 1,000 yard range, and recommends setting your zero at 200 yards when running this cant. If most of your shooting lives inside 500 yards, the 0 MOA sibling is the better pick, but for anyone reaching way out there, the extra angle buys you breathing room in your optic's elevation.
Fitment for the Winchester Model 70 Short Action
This base is drilled to drop onto the factory scope mount holes, so there's no machining your receiver. It fits the Winchester Model 70 short action along with the Marlin X7 and XS7 short action rifles. The center spread measures 3.259 inches, and it's always smart to measure your receiver's middle hole spacing before ordering to confirm the match. One thing worth noting: the Winchester Coyote edition in .243 uses the WSM mount instead, not this one.
Hardware and Mounting
The rail is ambidextrous thanks to a bevel on both sides, and the full-length cross-slots are cut to MIL-STD 1913 spec so your rings and optic sit true. Mounting hardware is included in the box. EGW calls for 20 inch-pounds of torque and a drop of blue thread locker on the screws for a rock-solid hold. At right around 2 ounces, it adds platform without weighing your rifle down.

Frequently Asked Questions
Does the EGW Winchester 70 20 MOA rail require drilling or tapping?
No. It's drilled to line up with the factory scope mount holes on the Model 70 short action receiver, so it bolts right on using the included hardware. It's a good idea to measure your receiver's middle hole spacing against the 3.259 inch center spread before installing to confirm the fit.
Should I get the 20 MOA version or the 0 MOA version?
EGW recommends the 20 MOA rail for shooting in the 500 to 1,000 yard range, since the forward cant gives your scope extra elevation travel. The 0 MOA base is the better choice for shooting inside roughly 500 yards. If you plan to run this 20 MOA base, EGW suggests zeroing your rifle at 200 yards.
What rifles besides the Winchester Model 70 does this base fit?
Along with the Winchester Model 70 short action, it fits the Marlin X7 and XS7 short action rifles. Keep in mind the Winchester Coyote edition chambered in .243 uses the WSM mount instead of this one, so measuring your receiver first is always worth the minute it takes.
What hardware comes with the rail and how should I install it?
The mounting screws and a Torx bit are included in the box. EGW recommends torquing the screws to 20 inch-pounds and adding a drop of blue thread locker for a secure, lasting hold. The rail accepts standard Picatinny or Weaver rings.
